Combine all the meats with the fresh breadcrumbs, grated onion, lemon rind, nutmeg, parsley, dried herbs,pepper & salt. Mix well, it's better to mix this together with your hands.
Bind with the 2 beaten eggs & mix well again.
At this stage you can chill the sausage mixture in the fridge - it's easier to handle when it is slightly firmer. You can also use the mixture for stuffing at this stage too.
When you are ready to cook the sausages or to shape them ready for freezing, form the mixture into sausage shapes - using a little flour to help you.
Dip the sausages into the beaten egg white and then dust lightly with the flour and set aside until ready to cook.
Heat up the oil and butter together in a large frying pan and cook the sausages for about 10-15 minutes over a medium heat. Turn them regularly to ensure they brown evenly.
Drain them on a paper towel & serve hot with mashed potatoes & onion gravy for Bangers & Mash or use them in Toad-in-the-Hole as well as serving them for cooked breakfasts & brunches. They are delicious served cold with chutney too.
I generally use a pre-mixed home-made dried mixture of Sage, Parsley, Thyme & Majoram. However any combination of dried herbs would be good - but NOT Rosemary as it is too pungent & will overpower the other flavours. One herb which is ALWAYS a must no matter what combination you use, is Sage - it has a wonderful affinity with pork & pork sausages in particular! I also use fresh herbs when they are available in my herb garden. Use at least double the quantity of fresh herbs as they are not as strong as dried herbs. Chop or mince very finely. Hope that helps!
