Maize flour seems to have a variety of names from different suppliers. It can be bought ground to fine, medium or coarse consistencies and is yellow in colour.
Maize flour ground to a fine consistency is called corn flour in America. What we call corn flour in the UK is called corn starch in America, which is what it actually is.
When my recipes list corn flour, I mean the white corn flour (corn starch). When my recipes list maize flour, I mean the yellow corn flour.
It can be also be called:
corn meal – the coarser varieties tend to be called this.
Masa Harina – this has been treated with lime, generally used for corn tortillas. This can be found in the specialist food isle in most supermarkets.
Polenta – a coarse variety.
