The theme for this evening’s cookery turned out to be Dishes That Require Four Ingredients. I didn’t plan it this way, it just turned out like that. Still, it’s nice to have simple good things up your sleeve, isn’t it?
For my actual supper, I was jonesing for greens so I ate a huge bowl of one of the most addictive kale dishes I’ve ever come across. I learned it from a good friend of mine who is, in addition to being a brilliant anthropologist, a phenomenal cook. She in turn cribbed it from a Thai restaurant, because she’s smart like that. Since learning this dish I have become kind of obnoxious about it and push it on everyone I know. They don’t mind, though, because it’s really that good.

Lemon-Sesame Kale
1 pound kale, cleaned, stripped from the stems, and torn into bite-size pieces
julienned or grated zest and juice of 2 lemons
2 Tablespoons Asian sesame oil
2 Tablespoons soy sauce
Steam the kale until it is just tender. Remove from the steamer, giving it a good shake as you do to remove any excess water. Toss with the lemon zest and juice, sesame oil, and soy sauce. Taste and correct the seasonings if needed. Eat.

For most people, this is probably not a complete dinner in and of itself, but then again, most people are unlikely to eat the entire thing in one go. I, on the other hand, am a kaleoholic, and am more than happy, upon occasion, to eat a pound of kale and call it supper.
I also did a little recipe testing tonight that sufficed for a very fine dessert. For the Mother’s Day brunch I’m cooking, I’ll be serving lemon and lime bars, so I wanted to remind myself of the go-to recipes I’ve used in the past for both citrus curd and shortbread, in case I want to change anything between now and the brunch. I may not — these taste pretty good.

Basic Citrus Curd
1 cup strained fresh lemon, lime, or other citrus juice
1 cup granulated sugar
8 egg yolks + 4 whole eggs
8 Tablespoons cold unsalted butter, cut into chunks
In a double boiler over simmering, but not boiling, water, whisk together the juice, sugar, egg yolks, and eggs until smooth, then stir gently until the mixture thickens to about the consistency of mayonnaise. This will take about 10 minutes.
If the mixture starts to form lumps, whisk ferociously and reduce the heat, and you should be able to save it. These are eggs you’re working with here. Too high a heat and you will have sweet lemon-flavored scrambled eggs. So just relax and take your time and do it over a simmer and you’ll be fine.
When the mixture has thickened, remove the inner part of the double boiler from the outer and place it on a bed of ice cubes. Add several chunks of butter and stir in until melted, at which point add more butter and repeat until all butter is incorporated and the mixture is smooth. Pour out into a scrupulously clean container, cover with plastic wrap (press the plastic wrap down onto the surface of the curd to prevent a skin forming), and refrigerate until thoroughly chilled.
Extra Credit: Strain the curd through a fine sieve before refrigerating. This will remove any of the small bits of chalazae — the membranes that serve as tethers for the yolk, holding it in place inside the shell — that might present as little chewy lumps in your citrus curd. Alternately, pour the uncooked eggs through a sieve before you start, which will do the same thing preemptively.
Simple Shortbread
The ratio for a simple shortbread is this: for each 8 Tablespoons of salted slightly softened butter, use one cup all-purpose flour and one half cup powdered sugar, plus one teaspoon vanilla extract.
The method, and let me tell you up front that you want an electric mixer for this, is to beat the butter until it is reasonably pliable, then add the flour, sugar, and vanilla and beat hell out of it until it comes together as a stiff dough. Trust me, it will happen, even though it doesn’t seem like it will at first. Do not yield to the temptation to add water, we are not making pie crust here.
Turn the dough out onto a baking sheet lined with parchment paper (or if you have Silpat liners, this is the time to use them) and roll 1/4 inch thick. Prick all over with a fork, which will release steam as the shortbread bakes.
Bake in a preheated 300F oven until the shortbread is golden brown and lovely. How long this takes will depend on how large a batch of shortbread you have made. Half an hour is probably the minimum, though, and it may take longer if you have made a large batch.
Remove from the oven, let stand 5 minutes, and cut while still warm into pieces of the desired size. Shortbread does not cut gracefully once it has cooled completely so strike while the iron is hot.
To make lemon bars, lime bars, blood orange bars, kumquat bars, grapefruit bars, or whatever other kind of citrus bars you fancy, simply cut the shortbread into bars, let it cool completely, then top each one with a layer of curd made with the relevant sort of juice. Sprinkle with powdered sugar if you like, though it isn’t really necessary.
If you want to get fancy-schmancy, convert your citrus curd into citrus mousse by folding a cup of it into a cup of heavy cream that has been whipped to stiff peaks, and make a lovely plated dessert with a slab of shortbread topped with a heavenly billow of mousse. A sprinkling of berries and perhaps a curl or two of citrus zest would be lovely, no?
