I want my chorizos to look like the sausages you present here. I'd be more than happy if I could achieve a unified/binded texture between the ground ant the minced pork.
Good to know! Your thread actually got me considering the opposite for a moment, as I haven't had a chance to consume the non-unified variety...
It's good then that your recipe doesn't include any acids, as @SmokinEdge's recommendation about vinegar was spot on. Even if you work harder on protein extraction and getting a sticky mix, the acids will get in the way of that smoother, more unified texture and make it grainier in the end.
I also experimented with how much meat I could mince and still get a unified smooth appearance in the end. In short, my "mostly coarse mince" product was awful without either a portion of the meat having a finer grind, or supplementing with binding element (like non-fat powdered milk) added to the mix.
Normally I like to avoid the "processed feel" that binders tend to add to my product, but it also adds more moisture retention. So if you're after something more industrial-looking, that could be something you may want to try adding to your product at 4g per kg of meat (though I wouldn't go as far as recommending it).
Was wondering wether 48 hrs curing in the fridge was ok or not. I live in a very hot place (35-40C°) and assume that with such room temperature range it is a bad idea to let them cure outside. Am I right here?
It's interesting that you ask, actually. We have an interesting discussion in another thread
about this topic. Given your butchers go as far as dyeing the meat (ick!), I think you certainly want the cure #1 to do its thing. You can also accelerate this process with something like sodium erythorbate. In any case, since you're grinding the meat, I think any of the following should be fine:
- Grind, mix, stuff, and hang at room temp (20-22C) for 2 hours. Hang in smokehouse (no smoke) until dry, then smoke.
- Grind, mix, stuff, and place in a cooler for 12 hours. Probably want an hour hanging no-smoke at 35-40C first to dry casings a bit. Then smoke.
I do feel that more time resting helps with flavor. So if I was doing this, I'd go with the cooler approach for 12 hours then dry casings in smokehouse. I wouldn't cure them outside at your temp range.
Hope that helps, and good luck!
