Lime, key lime or lemon curd – I love them all. Honestly, I find no difference between lime and key lime curd.

What is a curd?

Fruit curd is a dessert or topping, made usually with citrus.

Basic ingredients usually are beaten egg yolks (or eggs), sugar, fruit juice, zest and butter sometimes.

Ingredients are cooked together, until thick, usually over a double boiler.

After the curd is cooked, it is a good idea to strain it so it is extra smooth.

Curds are flavorful, soft and delicious.
