In Brazil they called them batatas à Portuguesa though I did have to ask what these were… Perhaps this is an example of cultural stereotyping. I did order them and as they were set on the table I immediately recognised them as my grandmother’s fries. Cut by hand (not on a chopping board) by holding the potato in the left hand and cutting towards your thumb with a sharp paring knife with the right hand (invert for left-handed I guess). My grandmother used to make them on a large shallow frying pan over gas with vegetable oil. I can never get that to work quite right (I cook on an Aga, you see…). So here’s my procedure when using a deep-fryer.
