doubling or halving a recipe

[frenchcreek]

I have a recipe I like for salmon. If I want to make double the amount of brine, do I double the salt, soya, etc along with the water. Same with a half batch - half the ingredients for half the water? I doubled one a while ago and it came out saltier than normal.

Double everything if doubling. Halve everything if halving.

Can I just move the decimal to the left on all of the ingredients, when measured in grams, to downsize the recipe?

If you move the decimal to the left in recipes that are given in metric units you are reducing by greater then half. If you move the decimal over one space you are reducing the recipe to 1/10th the original amount; move over two spaces you are reducing the recipe to 1/100th of the original amount.

So if you want to reduce a recipe to half the original measurements; whether it is U.S. or metric standards you need to divide by 2 or multiply by .50.
