You can do this by giving your sweetheart your heart – several hearts. It’s a variation on the food-for-romance idea.
Get a heart-shaped cookie cutter. A metal one works best. It can be any size, or maybe get a couple sizes.
Cut up some fruit (melon, cantaloupe, pineapple) into 1” slabs, slightly larger than the cookie cutter(s). With a smaller cookie cutter you could also use apples.
Use cookie cutter(s) as your pattern and trace the outline with a knife, cutting the fruit into heart shapes.
Present your sweetheart with the fruit tray, saying you’re giving her/him your heart. Have fun sharing this time together. Robert
