I love it when I get to try new flavors. Most of the time, that will mean it's something exotic. In this case, it was the kaffir lime leaf. The tree itself bears wrinkly, small green fruit and their leaves come in twos. It looks like two leaves end to end. They can be used for freshening up the garbage can or making Thai coconut soup. The leaves have their own distinct flavor and are very fragrant especially if you tear them. You might not be able to tell the difference between a lemon and a lime, but you can definitely tell the difference between a lime and this Kaffir lime leaf.
My coworker gave me a bag full of them and I used it to make ice cream. It was really good on this hot summer day. I used 3/4 cup of sugar, 1-1/2 cups milk, 1-1/2 heavy cream, handful of kaffir lime leaves, 6 egg yolks, pinch of salt.
