Spoiler alert -- I haven't found it yet.
I do have my mother's heart-shaped cookie cutter, though. This one was part of a 4-piece "bridge" cookie cutter set, circa late 1950s. There was originally a diamond, a clover/club, and a spade to go with the heart. Somewhere along the line, the other 3 shapes were lost or given away. My mom played bridge with some neighbor ladies once a month or so when I was small. I recall her using the "bridge" cookie cutters to make finger sandwiches. And of course, she always used the heart cutter to make cookies for Valentine's Day. I have several heart-shaped cutters, but I particularly like this one for its scalloped edge.
My mother never iced sugar cookies, instead preferring to sprinkle before baking with colored sugar, nonpareils, or those little rod-shaped jimmies. (I've got that covered. I used pink sugar crystals.) Her cookies were buttery, crispy, and held the scalloped edge of the cutter. Here's my problem, I have no idea what recipe she used.
I tried 2 recipes from her cookbooks so far and neither are it. The first recipe used a lot of flour. These are soft and cake-like sugar cookies that I make when planning on frosting afterward. The second recipe I tried was from her c. 1957 Better Homes & Gardens cookbook for Cooky-Jar Sugar Cookies. The recipe indicated that these were crispy. In comparing this second recipe to others that I found in cookbooks and online, the Cooky-Jar ones had a higher butter and sugar ratio to flour. I thought that would be a good start.
Sugar tends to add crispness to cookies and also encourages spread. A recipe higher in flour tends to produce a cookie that is tender and cake-like. Butter tenderizes the dough and aids in spreads if in high enough amounts. I wanted the crispness from the sugar, the flavor and tenderness from the butter, yet still holding the cut-out shape when baking (so, reducing spread).
I did a little reading on cut-out cookies. In addition to the right ratio of ingredients, it seems that the best doughs rest in the fridge overnight before rolling and cutting. To help maintain the cut-out shape, pre-baked cut-outs should be placed on a baking sheet and chilled for about 15 minutes before popping into the oven. So, I made sure to take both of these steps. I made the dough on Monday and chilled overnight. Then right after cutting out the shapes I chilled the baking tray and cookie cut-outs before baking. I do think those steps helped.
The cookies that held their shape the best were the re-rolls -- those rolled out from all of the leftover dough scraps, incorporating a little more flour than the initial dough. I think the BH & G recipe was close to what I remember from my childhood. The cookies were definitely crispy. They only partially retained the scalloped edge. But the flavor seemed to be lacking. I remember my mother's cookies tasting more buttery.
One thing I believe I did differently than my mother is I used all butter. My mother likely used half butter, half margarine. I don't know how that would have affected either the flavor or the spread.
Valentine's Day is just a few days away, so I don't think I'll be baking another batch of heart-shaped cookies. But I will be thinking how I can improve the flavor for the next time I make cut-out cookies.
My question to you, have you come across a recipe for a crispy sugar cookie that held its cut-out shape? Any ideas for improving the buttery flavor?
