From my point of view it is a corn thing.Sweet corn pudding - canjica - oooh so good. Then boiled whole corn served in the husk with butter and salt. Or, creamy corn polenta-like "pudding" combined with savory special ingredients - just like your grandmother used to make.
Everything designed to keep you warm on a cold winter's day.
Goddess bless corn.
Love me some Festa Junina.
