Kitchen Swap: Lunch at Abacus with Grilled Polenta and Mushroom Ragu
Every once and awhile, we superfans a` la mushroom just can’t help ourselves. We pick a city, find a chef and we sit down to eat together. And while last week’s luncheon at Dallas’ famed forno Abacus was filled with restaurant industry hot shots, they let a few unadulterated fans in as well. We’re so glad they did.
Two of our favorite Texans, Kelly from Evil Shenanigans and Temperance from High on the Hog, were able to join us for a mushroom-centric lunch from Abacus Executive Chef Kent Rathbun . It was a delicious way to bring what’s typically an conversation for us into gorgeous restaurant for delicious demonstrations and a new perspective.
Chef Rathbun wowed the guests with four courses of is trademark, inventive fare but Kelly made no secret of her personal favorite. We have all of the recipes prepared that day and will be sharing them gradually but in honor of our special guests, we’ll start with Chef Rathbun’s…
