Miso-Marinated Pork for Bento

Ingredients

6 slice Pork roast, (for tonkatsu) or loin
110 grams Miso
80 ml Sake
80 ml Mirin
70 ml Soy sauce
120 grams Caster sugar

Directions

Add the soy sauce and other marinade ingredients to the miso little by little, and mix well between additions to make the marinade.
Cut each slice of pork into 5 pieces, and put into ziplock bags of the right size.
Add 5 tablespoons of the marinade to each slice of meat, and let it sit in the fridge for 1 day to absorb the flavor.
If you're planning to freeze it, put it in the freezer after 1 day of marinating.
Defrost the meat right before using.
