Most people buy a vacuum sealer for food storage, but it’s just as useful as a cooking tool. It’s the key to sous vide cooking, it makes marinating faster and neater, and it turns batch cooking into ready-to-reheat freezer meals.

Homemade teriyaki marinade

This simple teriyaki is far better than most bottled versions and works with steak, pork chops, chicken and shrimp. Use it as a marinade in a vacuum bag or marinating canister, or thicken it into a glaze.

Recipe card

Homemade Teriyaki Marinade

  • Prep5 min
  • Cook5 min
  • ServesAbout 3 cups

Ingredients

  • 1 cup (240 ml) soy sauce
  • 1 cup (240 ml) water
  • ¾ cup (150 g) sugar, or honey to taste
  • ¼ cup (60 ml) Worcestershire sauce
  • 3 tbsp (45 ml) distilled white vinegar
  • 3 tbsp (45 ml) vegetable oil
  • 1 tbsp onion powder
  • 2 tsp garlic powder
  • 1 tsp grated fresh ginger
  • 1 tsp sesame seeds
  • Optional: hot sauce or fresh garlic to taste
  • Optional: 1 tsp cornstarch (to make a glaze)

Method

  1. Blend or whisk all the ingredients except the cornstarch until the sugar dissolves.
  2. To marinate: add enough to coat your meat in a vacuum bag or marinating canister, remove the air and refrigerate for 30 minutes to a few hours (shrimp and fish need only 15–30 minutes).
  3. To make a glaze: dissolve the cornstarch in a little warm water, stir it into a cup of the sauce and simmer until thickened.
  4. Store unused marinade in a sealed jar in the fridge for up to 2 weeks.

Notes

  • Never reuse marinade that has touched raw meat unless you boil it first.
  • With an external vacuum sealer, chill the bag so the liquid doesn’t reach the seal, or use a marinating canister.

Why marinate with a vacuum sealer?

Removing the air keeps the marinade in close, even contact with the food and stops it pooling in the bottom of a container — so you need less of it, and every piece is coated. Most of the flavour still stays near the surface, so don’t expect miracles with very thick cuts.
