Here is an interesting recipe for tangerine curd:

List of ingredients:

1/2 cup of tangerine juice.
1/4 cup of lemon juice.
2 tangerines, grated zest only.
1/4 lb of butter.
4 oz of sugar.
8 egg yolks.

Method:

In a saucepan, combine the fruit juices, zest, butter and sugar; bring to a boil over medium heat.

In a bowl, beat the egg yolks until liquid.

Beat a quarter of the boiling liquid into the yolks and return the remaining liquid to a boil over low heat.

Beat the yolk mixture into the boiling liquid and continue beating until it thickens slightly (about 2 minutes). Do not allow the curd to boil or it will scramble.

Pour into a clean bowl, cover surface with plastic wrap and chill.
