For my vegan friends wishing to enjoy gel desserts, I use the brand Natural Desserts Gluten Free, Vegan Jel Dessert I find at Whole Foods which uses no artificial colors. I simply use 1 1/3 to 1 1/2 cups water for every 2 cups water listed on the package so that it comes out with a decent firm consistency suitable for my family's texture preference. I avoid Kojel brand gel desserts as it includes fake colors such as Red #40 and others associated with behavior problems in children and skin issues in many people.
If you have a favorite brand of vegan or other piggy-free gel dessert, please let me know at firstname.lastname@example.org. I love your comments and suggestions.
