Lesson 2 -

Learning the ‘High Heat, low time, No water’ OPOS mantra

What is PressureBaking
PressureBaking is an OPOS technique of pressure cooking food in its own juices at the highest possible heat for the lowest possible time.
This produces dramatic results.
It heightens flavors, color, texture and promises greater nutrition.
It is just too good to be true.
OPOS & PressureBaking
PressureBaking is the core technique upon which other OPOS techniques are built on.


In a 2L PressureBaker, add 1/4C water, 1tsp oil, 2C chopped beans (250g), 1/2tsp salt, 1 chopped green chilli (1tsp). Close, fix weight and switch on the stove.

Cook on high for 2 Whistles or 4 minutes, whichever is earlier. Switch off the stove. Release pressure by gently lifting the weight. Open. Mix all. Marvel at the colour.


The 1/4C water you add is for beginners, as an insurance against burning. Most fresh vegetables/ meats can be PressureBaked in their own juices, with very little or no water.

  • Excess water? Repeat by reducing water.
  • Undercooked? Mix all & rest. Will cook in retained heat. Or cook for a whistle more.
  • Repeat lesson with your favourite vegetables.
  • Watery vegetables leak water. Cut them bigger.
  • Tough vegetables like Potato need to be cut smaller.
  • Edible greens shrink dramatically.
  • Okra needs to be wiped dry, cut big and PressureBaked only with oil to avoid sliminess.
