I stopped into a Penguin's Yogurt and found that they had Carbolite low carb frozen yogurt. It was fantastic! I found it on their website above.
They will sell it to the public, but in the form they sell it to the yogurt shops. You must add one bag of mix to one gallon of water. There is only chocolate and neutral mix. I bought both.
To make 1 quart of chocolate frozen yogurt:
2 1/8 cups mix
4 cups water
Mix in a blender for two minutes at lowest setting. Pour into your ice cream maker and let spin for 45 minutes. Tastes like Fudgesicle (spelling?) ice cream pops I used to eat as a kid.
To make 1 quart of creamy orange frozen yogurt:
2 cups neutral mix
4 cups water
22 drops yellow food coloring
4 drops red food coloring
1 tbsp orange extract
Mix in a blender for two minutes at lowest setting. Pour into your ice cream maker and let spin for 45 minutes. This is deeelishh, absolutely yummy. I think the neutral mix tastes better than the chocolate and I'm going to try a bunch of flavors. I'll update later.
This stuff stays soft in the freezer and is better after freezing a little.
