Just returned home from Mercado Del Progreso with the goods .
That lomo on hot placha 4 minutes with stove ON. Other side with stove OFF till it stopped sizzling (10 minutes).
8.5 years since I tasted and smelled meat like that .. (memory is coming back to me).
I`ll tell you ... Man!!! I am speechless, humbled in my content ..... glad I asked.
BTW, for sour cream I mixed 8 oz of Philadelphia cream cheese with 14 oz plain yogurt.
I am grateful to join baexpats, really really nice bunch, informative helpful and even fun to be around.
8.5 years late, but better than never.
