You should be able to find them in many major supermarkets. That’s where I’ve seen them the most but it is hit or miss. Sometimes they aren’t resupplied as often as lump charcoal.

There is also a brand that has a mixture of lump and briquettes. (can’t remember the name off the top of my head, but I do plan on giving it a try one day)

I would really appreciate much if you can inform me where I can find Briquettes here in Buenos Aires like the ones they use in the U.S.
made out of a mixture of wood coal, saw dust and blending materials as you mentioned here above.

Thanking you in advance

I remain
