Since you asked...

I suggest canned coconut milk (not the water)for evaporated milk substitute..which is THICK and SWEETENED (probably HF Corn Syrup too!)

I use this in VEGAN pumpkin pies for holidays with my Vegans.

Stevia is great sugarfree for sweetener ( I grow and dehydrate my own)

Heavy whipping cream - you will need the thickness and if it's runny - add a little gelatin packet from KNOX (unless you are VEGAN)

Thickening for VEGANS = Then add whipped chia seeds 1 teasp seeds to 1 TBSP water and whisk with a fork until frothy.

So STEVIA, whipping cream, canned coconut milk...good to go into freezer - will be like gelato unless you add the gelatin -clear unflavored packets.

Sorry, I digress but I cook at holidays for GLUTEN FREE (celiac) and VEGANS and Vegetarians and some meat eaters all. I have many special diet tips.

KETO is my new challenge as my husband is hard-core this year. Learning Keto -had MOCK-A-RONI and cheese last night.
