I'm still on SS but am anticipating 810 with great excitement! Just wondering if anyone has tried making celeriac into mash? I looked up a recipe and it included mustard - are we allowed mustard? Sounds yummy!!
Hmm, can only find a really old post that says 'no, it isn't allowed'. But having looked up the nutritional content, it's got about 1 gram of carb per teaspoon full (that's English or French). Colman's mustard has also got citric acid listed as an ingredient - but it's listed last, which means it'll be tiny tiny amount.
Best guess - a tiny amount wouldn't hurt, especially as on 810 you may not stay in ketosis anyway. Probably best to check with a CWPC though.
