Hi P360
A simple start would be to
brown off the portion of cubed Beef,
with oil,
onions,
2 Tej Patta,
2inch cinnamon,
5 cardamom pods.
Stir fry this in your pressure cooker for 5ish mins,
once it looks browned.
take a kettle and cover with boiling water (careful).
Pop the lid on and lock,
bring it up to pressure (high heat) then soon as its
up to pressure,
turn the heat down to low.
Let it cook for 15mins then switch
it off and leave it to release the pressure naturally (about 10mins)
Have a look and it should be tender, if not put the heat on low and slightly
simmer and stew until its perfect. (lid off)
Tip: Use a timer, 15 to 18 mins is all you need under pressure.
overcooking makes Beef/Lamb tough and it looses its flavour into the stock.
