Recipe by Thermomixer http://thermomix-er.blogspot.com/2009/04/mini-ham-and-asparagus-frittatas-in.html
1 large onion, peeled and quartered
150 g bacon or ham cut into chunks
30 g oil, olive or vegetable
1 Tbsp water
100 g asparagus spears chopped into short lengths
60 g milk
6 large eggs
Salt and pepper
Place the onion and bacon in the TM bowl and chop for 10 seconds on speed 7.
Add oil and water and cook for 6 minutes at 100°C on speed 1.
Place the asparagus pieces into the Varoma and steam these while sauteeing the onion and bacon.
To prepare the Varoma dish and tray: For ease, you can simply purchase greased patty pans and spray the insides with either cooking spray or oil, or use silicon patty pans. Place them into the Varoma dish and tray so they will support each other when filled.
You may prepare them in greased dariole moulds or mini muffin tins and place in the Varoma. You can even use plastic trays, or line the Varoma tray with a piece of silicon baking paper that has been crumpled, then wet and spread inside the tray, as in this post. With these last two methods you can cut the resulting frittata into small pieces for service.
Place some of the ham and onion mixture and some asparagus into the patty pans or tins/dishes. (If using the paper-lined Varoma tray, then just spread some evenly over the paper.)
Add milk, eggs and S&P to TM bowl and beat for 15 seconds on speed 4.
Add some of the egg mix to the moulds used. (If you have some left over, then transfer to a bowl and then wash out the TM bowl roughly.) Place some paper towel over the tops of the moulds to prevent moisture dropping onto the frittatas. You don’t need to do this if making a large frittata just using the tray and silicon paper).
Place 600 g water into the TM bowl and position the Varoma with moulds. Set the TM for 20 minutes at Varoma temperature on speed 2.
You may need to check after about 10 minutes depending on the size of the frittatas you make.
This method means that you do not have to turn on the oven and there is only the one dish to clean.
The frittatas freeze well and can be reheated in the Varoma if desired.
