I ask because I attempted a recipe for vegan "meatballs" today. The base was uncooked red lentils, which raised an eyebrow. Shocker, they tasted like raw red lentils (spices and sauce notwithstanding). The recipe also called for baking soda, so they exploded a little in the tomato sauce due to the acidity. 2/10 looking for a different recipe.
I wouldn't say it's my worst, though. One time I tried to hard boil an egg in the microwave. With the shell still on.
What's a culinary project that didn't go your way?
My personal worst was when I heard you could add yogurt to curry to bring the spice level down and since my mother had issues with the base levels of curry spice I figured I'd add a bit and make it more palatable. I hadn't realized that there was such a thing as plain yogurt so I assumed plain meant vanilla. So I add a whole package of vanilla yogurt to the curry. It was the most disgusting food I had ever made, the sweet vanilla flavor clashed so hardcore with the curry flavor that I just wanted to puke. Ruined an entire pot of curry in the process.
