Gather your supplies

Cut tomato in half

Make small incisions across the tomato, barely cutting into the surface (approximately half an inch). The tomato should look divided into sixths.

Make downward triangular incisions towards each cut.

Continue these triangular incisions all around the tomato

Make a tiny incision between the tomato and the skin in order to resemble a flower petal

Press the skin down with the knife in order to make them stick out more

Continue until you've done all of the petals

And done!
