The Cook's Companion by Stephanie Alexander has the goods. It is the best lemon curd recipe I've found. The key is to strain the lightly beaten eggs as you add them to the hot ingredients. I also use slightly less sugar than suggested as I really like tart lemon curd.
I'm off to make another batch as this jar is already half empty. I'm about to crank the oven and bake some Macaroni Cheese and Lemon Delicious Pudding for dinner tonight!
Have a good weekend!
