I have been reading a lot about making buckboard bacon and I was wondering is it possible to take a BBQ rub and turn it into a cure? If it is possible how do you do it?
Yes. It is easiest if you make the rub without salt or sugar so that thise can be added separately in measured amounts. You'll need pink salt as well of course.
Then, it's a matter of figuring out the correct proportions of pink salt to salt, sugar, and the rub ingredients.
Get an OHAUS triple beam along with a set of standard weights. Never ever purchase a scale without standard weights. All chemists know about this fact. Get a set of standard weights to accompany your scale for I purchased an OHAUS that was off by a couple of grams in 10g. And thanks to the standard weights I was able to exchange it for something more accurate.
I make a flavored dry cure for Montreal Smoked Meat. Just sort of tried it. The only two things I paid attention to was curing salt and sugar in correct proportion and that enough of it was used for the weight of the meat.
