Just a quick tip for all of us. Or at least another bunch of proofs supporting the oldest tip on NSD forums.
Coconut milk contains no starch, right? Right! Let's see ingredients:https://i.imgur.com/843jSF9.png
Only coconut, water and guar gum (which doesn't contain starches). Cool!
Then why Iodine gets deep purple?https://i.imgur.com/JpEduQM.png
Same with natural Ketchup- contain only tomatoes, vinegar, spices and iodine turns purple/black.
And same with Tomatoe Passata.
Test everything with iodine if you want to minimize starch because "contents" might be simply a big starchy lie!
