Total Time 55minutes
1stickUnsalted butterat room temperature, sliced into small pieces
1 1/4tspBaking soda
3/4cupButtermilkor milk soured with apple cider vinegar
1stickUnsalted butterbrowned and cooled
2 tbspPoppy seeds
Zest one lemon, into a medium glass (or heatproof bowl). Juice the rest of the lemons until you have 1/2 cup of lemon juice. Mix the juice, eggs, and sugar into the bowl with the zest.
Fill a medium saucepan with water to a depth of about 1 inch, and bring to a simmer over medium-high heat. Once simmering, place the bowl over the pan. and reduce the heat to low.
All to cook for about 20 minutes, mixing vigorously with a whisk every five minutes. The mixture should thicken up.
Add the butter one piece at a time to the pan, stirring gently and allowing each piece to mostly melt before adding the next. Once all butter is incorporated, turn off the heat.
Place plastic wrap over the bowl of curd, with it touching the surface. Refrigerate until fully chilled, for at least four hours and preferably overnight.
Preheat oven to 400F. Line a regular muffin tray with 12 liners and set aside.
Zest and juice the lemon. Mix the zest and sugar in a large bowl, rubbing the zest into the sugar. Whisk in flour, baking soda, cornstarch, and salt. In a medium bowl, mix together eggs, buttermilk, vanilla, browned butter, and lemon juice.
Add the wet ingredients to the dry, and mix until just incorporated. Fold in the poppy seeds.
Divide half the batter between the muffin cups. Add a tablespoon of lemon curd to the center of each one. Top with the remaining batter.
Bake for 18-20 minutes until golden brown on top, and a toothpick comes out clean of batter (there may be lemon curd on the toothpick). Let cool in the pan for 5 minutes and then continue cooling on a wire rack. Serve warm.
If you have an actual double boiler, you can use that to make the lemon curd. If not, match up your bowl and saucepan before starting. The bowl should sit on the rim of the saucepan, but not fall into it completely.
For the muffins, I use baking soda and cornstarch instead of traditional baking powder. You can use 2 tsp baking powder and 1/4 tsp baking soda if you prefer.
The curd may spread from the centers and stick to the muffin wrappers a bit. Just lick it off the wrapper. Worth it.
