What to do with a dry aged rump?

This is an interesting question as while we as Aussies love rump (or top sirloins as the Yanks call it) but we only really love it off the small and young domestic beef we do for the supermarket and butcher trade here.

We don't love big rumps as they have a small problem which is due to the fact that as the animal gets older the connective tissue "calcifys" which means gets harder and gristlier.

Now the rump consists of 4 muscles (see pic) all of which are covered in silverskin and there is a little bit of gristle around the place as well. So as a piece of meat it can suffer from the impression of being tough despite it not being the meat but the connective tissue that has caused the problem.




Now there is 2 ways to deal with this problem

1) trim every skerrick of connective tissue off

and

2) get the temperature of the connective tissue above 65 deg C at which point it will go soft so long as the cut in question is from a well fed and reared beef animal not some broken down old cow.

On the weekend I used both methods

Firstly and simply I made a version of steak tartare with completely denuded rump tri tip and eye of rump side. I made a spice blend with cinnamon, allspice, black and white pepper and salt. I then got some fine bulgur and washed it then pulsed it in a blender with a dash of olive oil till it was a fine paste. I pulped a few slices of red onion then blended my rump again to a paste like consistency.

I then worked the bulgur, red onion and meat paste together by hand adding the spice mixture as well. This was served with oven toasted pita bread



The remainder of the rump once trimmed was liberally doused in olive oil, scored and had salt rubbed into the fat. This was placed in a weber well stocked with real charcoal.

Set and forget and 3.5 hours later - it doesn't get any better than this

  1. The slow cooked rump sounds great. I don't have a Weber, only a hooded gas BBQ. I understand I won't get the same result as if using charcoal but can you recommend a temp I should get the BBQ to for a 3kgish rump and approximate time.
    I'm assuming yours turned out fairly rare?

  2. You should be fine with hooded gas BBQ - key to achieving the low and slow is getting the bottom of your rump off the grill in your BBQ a rack that lists your roast an inch or so should do the trick. I would get your temp to 120-140 then roast for 2-3 hours for 3kg - most important thing you can do is buy a meat thermometer - rump is best when you cook slow and internal temp is about 58deg
