Is anyone growing Chufa/Tiger Nuts? Eating them?

I found some of these in an African market.
I'm entranced by their high fat content, and fodder potential.
Like the nutrients of the tubers are similar to olives, and sedge has been successfully fed to rabbits.

I don't think they are actually the same as yellow nutsedge.
The bags of "chufa" sold for wildlife plots do seem to be cold hardy nutsedge, but I believe real chufa is  actually killed by frost.

Container growing seems like the best way to deal with the long growing times, frost sensitivity, and harvest difficulty.

So anyway, who has experience planting, growing and eating chufa?

I grew chufa last year, and saved the tubers to plant again. I love the flavor of them but didn’t eat many. I hope to try again this year and need to get mine out to plant. Hopefully they aren’t moldy. Thank you for reminding me!

As I recall I planted after frost and harvested in fall, like potatoes.
