Crawfish bought home use a toothbrush to clean it, because this shrimp lives on the ground and is omnivorous, so it is very dirty, you should scrub it carefully because when I cook, I leave the whole shell.
Melt 150g of butter in a large saucepan, then add the garlic and fry, until the garlic is fragrant, add the chopped corn + 2 onions cut into 4 + 1 sliced pineapple, stir well. Next, pour 800ml of water into it and boil for about 10 minutes, then turn off the heat, take out the corn separately and leave the pineapple and onions in the pot.
