Yes Mai, curcuma is that orange one that stains everything. Turmeric is more yellow, I think it's not the same but maybe they are different variations of the same plant, maybe they are treated differently during the drying process, I don't know for sure. The dosage is tricky. I don't measure but go with inspiration. Maybe it's better to put less cloves (the ones that look like nails ie. "clous de girofle") and cayenne (chili?) according to your taste. This is more than just about taste, it's medecine! Anxious to see what you have for us. My husband loves spicy foods, actually he is a better cook than me...He cooks like a man, he does "cuisine" while I cook like a woman, I just cook! And about the seven herbs, you can replace bay leaves by chives (ciboulette in French, the ones that look like grass and taste a bit like oignons).
