* Before squeezing a lemon, heat it in a microwave for about 15 seconds and then rub it back and forth on the counter top. This easy two-step process results in more juice per piece of fruit.
* Why not use the two extra egg whites to make two
Tequila Sours? Feel free to substitute another alcohol (such as whiskey or bourbon) if you prefer.
* Don’t worry if you mistakenly add the lemon zest to the rest of the ingredients before heating. I did this and it turned out perfectly fine.
* If you notice any small lumps in your finished lemon curd, you may have overcooked it. Simply push it through a fine-mesh strainer and it will be silky smooth.
