The GF just signed us up for a service called "Keto Krate" (
www.ketokrate.com). Once a month the company delivers to you a "krate" (actually a smallish cardboard box) containing a dozen or so small packages of keto-friendly snacks.
The first one came today; it contained items such as beef jerkey, meat sticks similar to Slim Jims, soft drink mix, snack "pastes", meringues, cookies, cheese crackers, and so on, all of which appear to be low-carb. I've tried one of the pastes, and the meringues.
The paste was similar to a thick chocolate syrup which you squeeze into your mouth from a small envelope. It was made with several different forms of chocolate, ground nuts, and a few other ingredients. It had a strange, bitter flavor which I didn't care for.
The meringues were very good; I couldn't tell them from the real thing. Unfortunately, they were sweetened with isomalt, and sugar alcohols do bad things to my digestive tract.
The GF tried the jerky/meat sticks, which she liked.
I expect that we won't be subscribed for too long; luckily you can stop at any time with no penalty. I thought it was worth the try we gave it, and maybe soon one of the snacks will stand out enough that we will order it on its own from another, cheaper source..
