3 Tbls corn flour
1 1/2 tsp seas salt
2 cups water

Mix all dry ingredients together.
In a medium saucepan place dry ingredients and heat on medium slowly pouring in water and whisking.
Once smooth allow to heat until bubbles form, always stirring.
Once bubbling, remove from heat and whisk in margarine.
