broil, parch, roast, boil
煎 centers on applying dry or wet heat to food: broiling, parching, roasting, or boiling. The common thread is cooking with heat, often to transform or prepare ingredients.
煎 combines 前 (before, front) with 灬 (fire). The character likely expresses the idea of applying fire to food, with 前 possibly contributing a phonetic element. The exact historical development is uncertain.
Picture a fire 灬 under a cooking pot, with the food placed in front 前 of the heat. The fire roasts, broils, or boils the food until it's done.
For セン, imagine sending a dish to be broiled over the fire: send -> セン, and the fire 灬 beneath the food 前 does the cooking.
