Mushroom Biryani cooked in Mr D’s Thermal Slow Cooker

Print Friendly

DAY ONE – this is my first of five recipes to celebrateNational Vegetarian Week.

I just love this biryani and have served it a number of times. It has an amazing depth of flavour and will be a hit with both vegetarians and non vegetarians.

Biryani originated in Persia and the name derives from the Farsi word ‘Birian’ How Biryani arrived in India is is a little unclear but one legend has it that Timor, the lame brought it down from Kazakhstan via Afghanistan to Northern  India. Another story is that Mumtaz Mahal (the beauty who sleeps in Taj Mahal) created biryani as a “complete meal” to feed the army. Other say the dish really originated in West Asia where the Nomads would burry an earthen pot full of meat, rice and spices in a pit, eventually the pot was dug up and there was the Biryani. 

The traditional way of cooking biryani is to seal the pot with dough to seal in the flavours. Mr D’s Thermal Slow Cooker does a similar job keeping in all the wonderful  tastes of the exotic spices.

This weekend we made two thermal cookers full for a birthday party and as usual it all got eaten.

Please give it a try because I am sure that you and your guests will love it.
