Razor Blade (Green Grape) Pie

Behind my grandmother's house in Hallettsville, TX grows an epic grape vine. As far as my mother knows, it's at least 70 years old since she's 71 and it's been there as long as she can remember. It's impossible to tell where the vine actually comes out of the ground or where the end of the vines reach, since they're draped and snaked around and through and over a chinaberry or hackberry tree and onto a huge oak in front of the barn. It's a source of wonder for my 9-year old who sees the mass of leaves and branches as a combination shady fort / animal graveyard (found an entire large animal's skeleton underneath) / potential snake lair.

I talked with the extremely nice Lavaca County A&M AgriLife Extension agent in hopes of identifying the variety of grapes. A quick internet search of photos of leaf shapes revealed that they're muscadine, not mustang grapes, but when they're ripe, they're white/green, not the bronze or purple named in A&M literature about muscadine grapes. The agent was also perplexed, so I emailed photos. The verdict is still out. I proudly told him the vine's been there since before my mother was born and he kindly informed me that there are a lot of those kinds of vines in Lavaca County. Whether the vine was planted by my grandparents in the late 1930s or, as my cousin Zoy speculated, it grew from the seeds of far away grapes first eaten and then pooped out by a wandering animal, we'll never know.

Last weekend my mother and son and I picked enough grapes for two razor blade (green grape) pies, in which a sweet custardy filling suspends sour, unripe grapes. Right now, my grandmother's grapes are still small and very tart, and the seeds are just developing, which is exactly how you want them to be for the pie. (The grapes will be ripe and sweet and ready for jelly or wine making in late June most likely.) I found at least a couple of recipes in community cookbooks at the house, but then my mother magically produced my grandmother's own recipe from a plastic bin of handwritten recipes we have yet to really go through. My grandmother continues to assist and watch over us in her house, though she passed away in 2012. Her recipe listed ingredients, but had no procedures, so we turned to a recipe by Mary Stary of Yoakum in the cookbook Sharing Our Best, published by the KJZT in 1994. We combined Ms. Stary's instructions and recipe for the posipka topping with my grandmother's list of ingredients for the filling.

Later, my mother texted me about eating the pie... "Thanks for the step back in time. Biting into a mouthful of those green grapes was yummy and mixed with emotion remembering Mother."

Though the flavor elicited delicious memories for my mom, I made the pie a second time and reduced the amount of sugar and increased the amount of grapes, because, really, the pie was awfully sweet. In general, I prefer not-too-sweet sweets and the zinginess of the unripe grapes was begging to be highlighted more. Increasing the amount of grapes warranted a deep dish crust, too, so below is the final recipe, un-sweetened a bit from my grandmother's version, with process photos.

What I love about the pie is the sweet-tartness, like eating lemon bars or key lime pie. I also love the "treat" aspect of the pie because it can only be eaten at a certain time of the year and you have to have or know someone who has grape vines. You can't walk into HEB or go to a farmer's market for unripe grapes (as far as I know.) In a food culture where we can have anything any time of the year if we want it, it's nice to eat by the seasons every once in a while.

I could not find even one single reference to "razor blade pie" on the internet among the billions and billions of bits of information out there. I don't know if my grandmother made up the name (it's sharp!), or where it came from. If anyone else has heard of this name for green grape pie, please let me know. Otherwise I just copyrighted it. :)

Razor Blade (Green Grape) Pie
adapted from recipes by Anita Kallus and Mary Stary

2 cups green grapes, washed and stems removed
1 cup sugar
1/3 cup flour
2 eggs
1/2 cup juice (from simmering the grapes)
a deep dish pie crust
posipka (recipe below)

Preheat the oven to 350 degrees. Simmer grapes in water to cover until just tender. Drain (reserving 1/2 cup "juice") and set aside. Sift the flour into the sugar and combine. Beat the two eggs well, then add the juice to them and mix together well. Mix the flour-sugar mixture and the eggs-juice mixture together in a large bowl. Add the drained grapes and combine well.

Pour the pie filling into your unbaked crust. (It looks to me like a pie full of creamed giant peas!)

The pie will bake for 1 hour, but set your timer for 30 minutes when you put it in the oven and make your posipka while it bakes.

1/4 cup sugar
1/4 flour
1/4 cup softened salted butter

Combine the ingredients above first with a fork while you mash up the butter, then with your hands to really combine everything into a crumbly mixture.

After 30 minutes of baking, take the pie out and crumble the posipka evenly across the top.

Put the pie back in for another 30 minutes. Let it cool and set before you slice it.

Like most pies, this recipe makes 8 servings if you have little restraint, but 12 servings if you do.

Good things happen when grandmothers and grandsons pick fruit and bake together... pie!

  1. Razor Blade Pie! It sounds amazing. Thank you for sharing the story.

  2. What a wonderful story and tribute to your grandmother. And now you’re continuing the tradition with your son and his grandmother. That box of your grandmother’s recipes is a true family treasure - along with that huge and amazing grape vine.

    1. Thanks for reading, Linda! I so agree about the family recipes. Handing down recipes is a way to keep giving to your family even after you're gone. :)

  3. Thanks for posting this! My grandmother's from the area and remembers her mother making green grape pie with the mustang grapes that grew on their land. She said she always found it a little too sour; maybe the secret to success is those hybridized grapes!

    1. Thank you so much for reading! The grapes are still sour in my pie but the sweet custard and buttery pie crust help balance the flavors. Try it if you can (especially if you can get your great grandmother's recipe. That is a treasure!) -Dawn

  4. Dawn, I just found your blog thru FB, the cucumber and tomato salad!! I didnt know this was your site, how very secial, proud of you and intrigued! Cousin Karen M

    1. Hi, Karen and thanks for reading. So sorry for the late reply. Hope you're have a delicious summer. -Dawn

  5. My aunt told me about being sent out to collect green mustang grapes to make pie when unexpected guest would turn up. I've never eaten it, but now have a greenhouse full of unripe purple grapes, so I may try making a pie with some of them.

    1. I'm a Texan now living in Scotland, hence the greenhouse full of grapes. :-)

    2. Sorry for the late comment reply. Scotland!! My older son's father's family is from there. The first time I had rhubarb crumble was the first day we visited Scotland way back when (also has a sour aspect to it.) I'd love to know if you tried the pie and thanks so much for reading. -Dawn

How to Eat Texas Czech in October

October is Czech Heritage Month in Texas. What a fitting excuse to eat and learn about Czech and Texas Czech traditional foods. At the bottom of this post are several events at which you can do just that.

If you want to cook Czech food in October, by all means cook local and seasonal. In Texas in October, there are lots of fruits and vegetables to buy at your local farmers market that are widely used in the Texas Czech kitchen. Here are some suggestions.

apples and pears - make kolach fillings, pies, and bundt cakes, or pear preservescauliflower - make fried cauliflower or pickled cauliflowercabbage - make sauerkraut, fried cabbage, zelniky (cabbage kolaches), slaw, or sauerkraut saladokra - make stewed okra with tomatoes
Last weekend I tried yet another sauerkraut recipe (pictured above), this one with apples and potatoes. It was just the right balance of sweet and sour and rich and tangy. I used Granny Smith apples so things didn't get too sweet and served it with pan-fried sausag…

May Fest and 24 Kolaches

Sometimes a person just needs 24 kolaches. I have dough recipes that make as many as 6 dozen, but sometimes I just need 24… staff appreciation day at my son’s elementary school, or a monthly staff meeting at work, or (today) a contribution to the dessert table at Slavnost (May Fest) at the Texas Czech Heritage and Cultural Center (TCHCC) in La Grange. I am a member of the Travis-Williamson Counties chapter of the Czech Heritage Society, but hardly ever go to meetings. The chapter was in charge of the dessert table at the event today, so I decided to finally volunteer with them and also contribute something to the $1/dessert table. I failed to ask what they needed, so brought a pan of kolaches, which the event actually buys from Weikel’s in La Grange.

Other chapter members and TCHCC supporters – all experienced bakers and dessert makers – brought poppyseed and other cakes, apple strudel, pecan and cherry pies, cookies, peach cobbler, brownies and other delicious things.
I wanted to br…

What I Learned Making 600 Kolaches

The last week in July, I launched a home baking business called Old School Kolaches, offering pans of made from scratch kolaches, delivered to customers' doors. I got laid off in April and in reaction to scrolling endlessly through disheartening job boards at 50 years old, I decided I'd try doing something I'm good at and passionate about that also pays some of my bills (work and love don't always go together unfortunately.) It remains to be seen whether this can be instead of or in additional to a standard 9 to 5 job for me.

Austin, though it's the state capitol, is a wasteland when it comes to traditional kolaches. The one place I went to here that had decent kolaches closed down only weeks ago. There are instead two kolache bakery chains, countless donut shops that offer hotdogs wrapped in croissants or tasteless dough and call them kolaches, or one hipster beer and kolaches place that "elevates the classic Central Texas Czech pastry to gourmet status" …
