NOTE: for individuals who think this really is healthier than high fructose corn syrup. The objective of the cream of tartar would be to break the sugar lower into glucose and fructose. So most likely no much better than storebought from the health perspective. Some recipes need these simple sugars to prevent crystals developing (eg chocolate, some frostings) however for other purposes (eg pancake syrup) maybe easier to locate an alternative if health is the motivation.
It might not be "healthier," however for individuals having a corn allergy, this may be an excellent recipe. My 6 years old boy has missed getting marshmallows since he was identified as having a corn allergy last year, now we are able to make sure they are in your own home. ) Just recipe!
I only gave this 3 stars because the published recipe unsuccessful. I attempted it again doubling water which labored perfect. I additionally feel it ought to be noted this takes almost one hour to prepare. It should be gradually simmered. The very first batch I cooked to rapidly also it switched to hard sugar.
