I use Indian beef. To cook beef: Close the cooker and put on weight. Cook on high flame, till the first whistle comes. Reduce flame to the lowest and cook for 10-12 whistles. Switch off and keep the cooker closed till pressure drops, around 15-20 mins. The cooking time of beef may vary depending on the type of beef you use. The curry keeps well in the fridge for 2-3 days.
