Yup, raw rhubarb is sour/tart tasting. As kids we would grab a stalk, break it above the “heart” dip them in the sugar bowl and munch away. A family friend made exceptional rhubarb rolls with sponge cake(?) lightly dusted with confectioners sugar. Her secret rhubarb fill was summer perfect slightly tart tasting...hard to describe it. Mmmmmm!!
I’m not ready to pay $5 per pound. But I’ll remember ‘Mmmmmm’ when I find it cheaper somewhere :-)
