Have you any luck with organs?
I am in Frankfurt. Where can I buy FAT? (online?)

have you tried a butcher?
i'm in the filipines and pork fat is abundant in the wet markets.  also, on sundays, it's common for ppl with backyard pigs to set up a roadside table with freshly butchered pigs.

i've been low carb, meat based in the filipines for about 2 years and having trouble with the heat.  the heat never bothered me with a heavy fruit diet; just eat more watermelon. 

thanks guys, nice vid!

oppsss,i just learned about freeze driers.

The local butchers do not supply fat trimmings, if butter is no good I'll have to eat tallow.

get some beef belly and mix it in with whatever ur eating.

also, search fatty cuts of beef

i feel i should add a bit to my post:
maybe ur a newbie to animal based diets?
u didn't give us any background on your situation but many health gurus are recommending doing an elimination diet to get to the root cause of your health issues; the carnivore diet seems to be a popular diet to do that.

search both kidney and high blood pressure on dr. berry's you tube site.
here's one of his monday nite live podcasts; he mentions paleo and other animal based diets at 9:15.

his monday nite podcasts are a good watch!

none of the above is raw but should work for raw also.

i've been doing something similar to make a diy LMNT

following the ingredient proportions on a LMNT packet; 1k sodium, 200mg potassium, 60mg magnesium.
i spread the ingredients out on a 1m x 1m sheet of plastic and rolled it back in forth until well mixed, then stored the mix in air tight jars.

i've been adding 1 teaspoon to a 650ml water bottle for drinking and also using the mix as a salt on food.

i was still having leg and hand cramps after using it for a month so i started mixing 1/4 tsp of magnesium powder to a cup of my LMNT drink and i haven't had any cramps since.

also, i was having swollen lower legs (water retention) so as an experiment, i quit all salt/LMNT for 3 weeks and my leg went back to normal.  i maintained taking magnesium during the saltless period and no cramping.  i'm going to start slowly retaking my LMNT and find my limits.

Is dry-aging the way to achieve what I want?  Or am I just going to be making raw beef jerky?

how thick are the slices ur trying to age?  mine are thin (~3/16''/5mm), it's for snacks.  i don't have any experience with anything thicker than that but i would think much thiker, one 1 for example, would form a crust and slowly dry from the outside in and be difficult to eat.  proper aging requires a combination of proper temperatures and *humidity.*

sabertooth has a post on here about his meat storage fridge that looks to be more what ur looking for.
also, wet aging might work for you.  there's lotsa info on the web on aging meat.  one site i enjoy is the bearded butcher; truly skilled artisan butchers.

i'm in the bush in the filipines and i get my beef from the slaughter house vender at the local wet market where it's hung in crudely cut up chunks or strips and displayed on hooks, nothing like the plastic wrapped products u see in a supermarket.  works for me; i usually get a chunk of chuck, a heart and some liver and grind it; currently 8kilos chuck, 1 heart (~850g) and 500g liver.  i sometimes add a kidney or two and or a brain.  i was adding fat, which they give me for free, but i've learned that too much fat gives me diarrhea.

i recently found some of my jerky, forgotten, in the freezer, in an open bag and it's too dry but still chewable.  it had been in the fridge for at least 2 months and i wasn't eating it so i moved it to the freezer.  it's at least 6 months old now; it's still a good chew but i wonder about it's nutritional values.  the fat on the slices gets crispy; kinda nice...

So you mean a plastic bag under the ring and band parts? Doesn't this prevent the jar from actually sealing properly?

sorry i wasn't more clear.  i think a canning jar with a good lid will give you as tight a seal as ur going to get.  you could put a poly bag over the canning jar lid and screw the ring down for insurance but the poly bag itself isn't going to stop the odor.

i'm in the filippines and i use poly bags for recycled jars, canisters, lidded cups, etc. that don't have lids with good seals/gaskets.  for instance, i have a salt jar with a plain lid (no seal) and i lay the side of a thin poly bag over the opening before i put the lid on so there are actually two thicknesses of bag.  it keeps the salt from caking.  also works for herbs/seasonings.

i have a 1liter poly jar with a plain lid that i use to get young coconut juice (buko juice) from a street vender. i put a poly bag under the lid and it keeps the juice from leaking out as long as i keep the container upright (on a motorcycle).  sometimes, i'll float a tomato or something similar in the jar; it helps to keep the juice from sloshing up the sides of the container.  i learned that trick by transporting water in open top barrels with a piece of wood floating on the water but now i'm getting off topic...

it must be something in the water
