Buy a good quality corn oil - available from health food stores. Like all oils, if using in small amounts buy little bottles.
Best stored in dark, glass bottles in a cool pantry away from direct sunlight.
Tips & Tricks:
Because it has an extremely mild, sweet flavour, corn oil can be used instead of butter for baking.
When substituting oil for butter use less oil than the recipe calls for butter.
Use 1.5 Cups wholewheat flour to 0.25 cups corn oil and a small quantity of water to mix to a pastry dough.
