Kangaroo and vegetable casserole

Kangaroo is a delicious meat and I bet there aren't too many Thermomix recipes around for it. So here's my first one:

Kangaroo casserole
1 onion
25g butter
2 carrots, cut about 2" long
some pieces of celery, cut about 2" long
500g kangaroo, diced roughly 1"
100g mushrooms, quartered
100g wine (I used white but you could use red)
100g water
2T stock concentrate
1/2T tomato paste
1tsp seeded mustard with chilli
1T cornflour
1 bunch of asparagus

Put onion into Tmx. Process for a few seconds at speed 7. The carrots and celery go in for a few seconds too but don't mince them - just break them up a little. Add the butter, set to 100C and speed 2 on reverse, and cook for 3 minutes. Add the rest of the ingredients except the asparagus, and cook for another 20 minutes at 100C on reverse, speed 2 so it's stirring well. For the last 2 minutes, add the asparagus - I just cut it into 3" pieces and stuck it through the hole in the lid and it was perfect!

Serve over rice. Or pasta. Or with mash. Or whatever you like.

Inspired by the Beef Stroganoff recipe in the EDC but adapted for kangaroo, the derth of ingredients in my pantry and fridge, and the need for iron. And asparagus in season!!
