Citric acid? Do I find it next to white vinegar in the supermarket and does it have a very different french name? Would love to add it to my repertoire

You can get it in supermarkets, in the cleaning stuff aisle - Briochin do it, also bicarb, fullers’ earth etc. You can also get it in brico shops and bio shops.
