I know I’ve posted about this in the past, but I’ve had another go and I thought you might be interested in the results.
Part of the problem with the previous recipe was that it made gallons of starch! Although I managed to use up all of what I had without mishap, it did start to degrade as I got to the bottom of the jar.
So if you’re not starching a dozen hankies for each member of the household plus tray cloths and doilies, here’s the revised recipe.
Vintage Starch1 teaspoon cornflour 1 teaspoon cold water Mix to a paste. Add 275 ml boiling water and stir until smooth Top up with 125 ml cold water. Immerse items in starch, squeeze out excess and hang dry. Iron when damp.
