Hi ES

Yes, lard is pretty much pure fat, but the way the fat breaks down in the stomach effects how much THC you'll get into your bloodstream.
Without getting too technical, the best fats are short to medium chain fatty acids which can pass through the stomach lining quickly and don't get too 'worked over' by the bile acids.

Lard doesn't contain as much of this type of fat as regular butter (which is around 60+ percent) or clarified butter (around 80 to 90 percent). Best of all in my experience is coconut oil/butter as it contains around 90-ish percent, is a healthy option and tastes great too! lol. The downside though is it can be a bugger to find, so clarifying regular butter might be an easier option.

You can still use your lard however, and it'll still work, but if you were to run a 'side-by-side' comparison you'd see quite a big difference in the amount of 'high' you'd experience (edit: even if you clarified the lard). So you'd almost certainly end up using less overall, and therefore saving yourself money and weed.

The really good news is, it sounds like your shake is going to be pretty potent (a recipe is only as good as its ingredients), and you've got a crock pot too which makes things much easier, and gives you more options.

I've got a couple of methods in mind that I think will do the trick, so I'll post them up in a hour or two when I get back to my computer after finishing my own cooking session (the weekends coming up and I need to be stocked up myself lol).

Cheers
