I have just tried to make this in the Thermomix, but have given up and put it in a pan. The recipe said to cook for 45 minutes, but after 6o mins there was no sign of the liquid reducing at all and it was very runny.
The recipe has 5 sliced onions sweated in oil, then 250 mls of port and 250 mls of sherry added. Recipe says to cook down for 45 mins. I only put in about 200 mls of each of the fluid, because I thought that it might not evaporate as much, but this is ridiculous!
Obviously there is some hint that I am missing!
Anyone help?
