This is an adaptation of an African street food dish called Abala. In Senegal, the little packets are wrapped in banana leaves. At one time I had a banana tree in my yard, and could harvest my own banana leaves for wrappers. I used them to make a Burmese dish of steamed sweet rice – yum. But I digress. If you don’t have your own banana tree, there are plenty of banana leaves for sale at the DeKalb Farmers Market in both fresh and frozen form, and probably at any store that caters to a Caribbean or African customer base.
Or – make it simple – use corn husks as I suggest here. Those are pretty ubiquitous these days.
Just reading through the recipe will remind you that many cultures have leaf-wrapped dishes with a starch – like field peas or corn masa – surrounding a savory filling. And the relish here? If this were a recipe from Mexico, we’d be calling it pico de gallo.
