How To Make Sugar Free Keto Simple Syrup:

• Allulose is slightly less sweet than sugar, so the ratio isn't 1:1. Use about 1 and ⅓ cups allulose for every one cup of water. 
• Bring the water to a boil, and stir in the allulose. Remove from the heat and continuing stirring to dissolve. Allow to cool before using. That's it! Store in an airtight container indefinitely if kept in a cool, dry place.
• If you choose a different sweetener to make your simple syrup with, but please note that many (non-sugar) sweeteners will crystallize after being refrigerated.  

Keto Substitutions:

• For full fat coconut milk: Honestly, we don’t have a good substitute for full fat coconut milk, unless you want to go even heavier, and get coconut cream. This will add more calories but it will also be super creamy. Make sure you’re always reading the labels! Creme de coco is not the same thing as canned coconut cream. (Confusing, we know). In fact, that’s what we are trying to avoid. It’s packed with sugar! You could also probably take coconut cream and thin it just a bit with unsweetened coconut water. (It’s just a thought, we haven’t actually tried it ourselves!)
• For keto simple syrup – You could use any sweetener you want here. Something liquid would probably be best, but you could also use granular since this drink gets blended.
• Pineapple – We would not recommend fully substituting the frozen pineapple, even if you’re trying to cut carbs. It just won’t be the same! However, you could use a little bit less frozen pineapple, and replace it with some pineapple extract, and a little bit of extra liquid.
