Something my DH came up with. Lancanshire relish sauce is similar to worcestershire but sweeter (they use fruit in the cooking process). It took 2.6kg (5 3/4lbs) of gravy/shin beef to get 2kg (4 3/8 lbs) and 600grams (21ounces) of skirt to get 500grams (17.6 ounces)(Trimmed of fat and grissle). The cup measurements for the vegetables is peeled, cut/diced. Prep time is based on you doing this, buying predone will save time but you could do what I did and got the kids involved DS and DH and had them doing the peeling and dicing while I did the rest. Sometimes it took longer but the memories are irreplaceable.
