My butchery/slaughter costs, including vac-packing and putting in the boxes (boxes supplied by me) were £300 all in.
I asked the butcher to put the following, to add up to 10kgs, in each box:
- 1 roasting joint
- 1 slow-roasting or braising joint
- some steaks
- some stewing steak (diced)
- some mince
- some burgers
He ended up doing joints about 1.5 to 2kgs, all the other packs were approx. 1kg. (9 burgers made 1kg, 4 steaks.) So far no-one has complained (quite the reverse) but when I do my next one I may get some requests for slight variations in content, of course. One of my customers had no burgers and extra mince, as she needed gluten free.
Working this way worked well, we got 8 boxes comfortably, another box where a few substitutions had to be made (which was for my family, so no problem), and about 26kgs over which was my share.
This was a Jersey heifer, unsuitable for breeding. Deadweight 193kgs at slaughter, grade -O3.
I charged £10/kg plus packaging, with a bit of discount for friends.
All the packaging was new, I didn't let people bring their own because it made it too complicated for the butcher. Good packaging isn't cheap, and it costs a bit to deliver. If you can store boxes you can order in bulk and it'll come out cheaper. For me, it added £6.31 for a customer who was coming to me or the butcher to collect, add a further £1 for the cardboard outer for a couriered box. Packaging included chiller strips - the ones you wet and freeze yourself.
I was pleased and surprised at the number of customers who were happy to pay to have a 10kg box couriered to them. So I didn't need to find all my customers locally, or prepared to drive to me or a convenient rendezvous.
