, lemon rind, and
to a small saucepan and heat to a boil.
Cook until the blueberries burst and have broken down into a sauce - about 5-7 minutes. Remove from heat.
Set a fine mesh strainer over a small bowl. Pour the blueberry sauce through the strainer. Use the back of a wooden spoon to press on the blueberry solids, pushing them through the strainer. Do this until the only thing left in the strainer are the blueberry skins and the lemon rinds. Discard the solids. Cover and refrigerate the blueberry puree.
Large Eggs (6)
in a medium bowl and whisk them together.
Heavy Cream (1 1/2 cups)
to a simmer in a heavy medium-sized saucepan. When cream is hot, slowly whisk it into the egg yolks -- adding the cream a little at a time so that the eggs don't heat too quickly and scramble.
Pour the egg mixture back into the pot and stir constantly over medium low heat until custard thickens slightly. Remove from heat.
Place a fine mesh strainer over a medium bowl and pour the custard mixture through the strainer.
Allow the custard to cool slightly.
Then stir in the
La Lechera® Sweetened Condensed Milk (1 can)
Key Lime Juice (1/2 cup)
. Cover and refrigerate until cold or overnight.
Make the ice cream according to the manufacturers instructions for your ice cream maker.
Transfer the ice cream to a loaf pan or other storage container, cover with plastic wrap and freeze for about 20-30 minutes so that it firms up, but isn't hard.
Scoop out one quarter of the ice cream and add 2-3 tablespoons of blueberry puree. Use a spatula to fold the puree into the ice cream. One or two turns with the spatula is all you want -- so you get pretty swirls. If you work it too much -- the whole thing will turn purple.
Transfer into a new loaf pan. Repeat this process with ice cream and puree until you've used all the ice cream. You will have leftover puree, which can be spooned over the top of ice cream before serving, or use it for other desserts or cocktails.
Freeze the ice cream several hours or overnight.
Scoop and into bowls and serve.
