How to Use the Recipe Scaler

The scaler doesn't need to know what ingredients you are using - ie , if it is butter, flour, eggs etc.

It only needs to know the WEIGHT of each ingredient.  So simply go down your ingredient list and enter a weight for each one - you just need to remember which is ingredient 1, which is ingredient 2 and so on.

The weight can be in grams, kilograms, ounces or millilitres.  You only need to enter a number in the box, not the unit of measurement.  The scaler will work in the same way for any unit of measurement, and it won't matter if some ingredients are entered using imperial weights and others in metric.  You just need to remember which unit you used for each ingredient, so you can use the same unit to measure out the amount given in the 'results' column.

The 'result' may end in a tiny fraction of a gram, as the scaler is VERY accurate!  You can just round it to the nearest sensible number, depending on the unit you are using.  EG rounding to the nearest whole number is fine if you are using grams.  If you are using kilograms, pounds or ounces you will still need to pay some attention to the numbers after the decimal place!

Good luck!
