There has been some discussion on turkey mince recently.
You need to read the label and check the fat content. There are huge differences between different brands - between 0.8% and 9.9% in the ones I looked at. You really need to keep it below 5% if possible.
If you find it's not a lean mince, then do what I always do with any mince (mostly because I can't stand the taste of meat fat!):
Dry fry the mince on it's own in a pan until it is cooked, then drain it through a large sieve and rinse under hot water. You'll get rid of most of the fat that way! It's interesting to see just how much fat comes out of mince... :jelous:
Then just add back to the pan with fry light and voila - syn fee mince!
Just remember not to sieve it down the sink, or else you'll end up with blocked drains!
