Have you ever made a recipe that calls for part of an ingredient? Say, a few egg whites but no yolks, or lemon peel but no lemon flesh? The wonderful thing about culinary history is that thrifty cooks throughout the ages have come up with wonderful ways to use these castoffs. So when I decided I wanted to make macaroons, which require egg whites, I knew exactly what symbiotic recipe I wanted to use to keep my surplus yolks from getting lonely: lemon curd.
As you may or may not know, lemon curd is a delightful concoction made from egg yolks, lemon juice, sugar, and butter. It gets cooked into a creamy spread that is heaven on scones, toast, muffins, or anything else you can think to spread it on. It’s just tart enough to balance out the heaviness of the yolk and the butter, and it’s the most delectable shade of yellow this side of a daffodil.
I used this recipe from My Kind of Food and this recipe from Joy of Baking for my curd. The first gave me the basic ingredient proportions and the second told me how long I had to cook it. I ended up using the juice of two smallish lemons, 3 egg yolks, 7.5 tablespoons of sugar, and 4 tbsp butter. I whisked everything but the butter over a double boiler for 10 minutes until it took on a thick, creamy, sauce-like consistency, then took it off the heat and whisked in the butter one tablespoon at a time. Then I licked the whisk and almost cried. Yes, it was that good. I’m glad I went with 7.5 tbsp of sugar – it’s just the right amount for a tart-but-not-too-tart taste.
I’m afraid my poor camera won’t do it justice, but here it is:

I was pretty full when I made this but I needed to eat some fresh, so I spread a bit on half a slice of bread.

I kind of love that it looks like mustard gone wrong.
And what about those macaroons? Well those, my friends, were an abject failure. I make the mistakes so you don’t have to.
I used this recipe from Elana’s Pantry, but the failure was certainly not Elana’s fault. I realized as I was beating my whites that it had been some time since I’d done anything with egg whites and I wasn’t sure that I would recognize “stiff” egg whites when I saw them. It was too late to do my research though, so I just beat until I thought they were stiff. In retrospect it wasn’t nearly long enough. I also realized too late that I didn’t have enough agave, so I subbed in honey, which is much thicker than agave and more difficult to fold into fluffy egg whites. Fail, Daria, fail.

This isn’t what macaroons should look like. They should not be shiny or flat or oozing. They should be covered in chocolate though. At least I got that part right:

So now my homework for myself is to read up on the chemistry of egg whites. I’ll report back on my kitchen dictionary page soon. Because no one should have to eat flat macaroons.
