A wonderful, bright orange creamsicle flavor in a smoothie or popsicle.
1/4 cup nut milk, any kind
Put all ingredients in a blender and blend it up. Put the kumquats in whole. You may have to let it go for a while to get the kumquats completely blended in. Drink as it is or pour into ice cube trays or popsicle molds for a frozen treat.
Feel free to double or triple the batch if you're making popsicles.
Just in case you don't know, kumquats are very much like grape-sized oranges. They are often found in the produce section of the grocery store near the mushrooms and other refrigerated produce. They have a very strong flavor, so you don't want too many.
