Rinse the sesame leaves well in cold water, then drain.
Crush or chop the garlic.
Put the soy sauce, sugar, garlic, and chili pepper in a small pot and heat over medium heat until liquid just begins to boil.
Reduce heat, add sesame leaves and simmer for three to five minutes, turning often.
Remove from heat.
Use a small strainer and remove leaves from the liquid. Set strainer over the pot so that liquid drains back into the pot, and let cool.
