Well, I should have started there! Every week, I have to work out recipes with a focus on seasonal ingredients; for example here in France, the products of the month of January are (not exhaustive list): pineapple, avocado, banana, beet, carrot, etc. When I click on a query -that remains to be built- I want it to tell me if the ingredients provided in the recipe are seasonal or not; moreover, I want this query also return to me other purchases that are not seasonal (ginger, pasta, cheese, etc. I hope this is clearer for you. Thank you for your help and patience.
