Both.
When I try a recipe from a cuisine that was a Cuisine of the Quarter, when I try a recipe someone recommended, when I find a recipe that that worked that I want to share, when I’m seeking our specific dishes or recipes, sometimes when I order the dish at a resto, and occasionally when I see an article that relates to the topic.
I mostly add recipe links to the Greek, Japanese, British and Slavic Cuisine of the Quarter threads.
Today I was adding tomatokeftedes / tomato fritters recipes to the Greek COTQ thread, and I made them tonight.
