Review of Cactus Flavor-INW:

Tried 0.5% in a blueberry custard (5 drops in 50 ml) and after a week I get floral notes. It does remind me of a succulent like a cactus or aloe. I'm going to try it with some kiwi and coconut as it would seem a good possibility for enhancing and rounding out tropical flavors. 
Not recommended for fruity custards.
