Irresistible Peanut Butter Ice Cream

What is it?

Peanut butter works as a swirl rather than a flavouring because of its fat and salt. Blended through evenly it flattens into a mild nuttiness, where kept as a ribbon it stays thick, salty and distinct against the base around it. That's what happens here. The swirl runs through the tub rather than sitting on top, so a scoop can land mostly on the plain base or mostly on the peanut butter, and the salt arrives unevenly rather than as a constant. It's part of Coles' Irresistible label, which the supermarket uses for its richer own-brand desserts. This is the most savoury flavour in that line, and the salt is what separates it from the caramel and chocolate tubs beside it.
