It's a Polish gingerbread cookie; the original measurements are in metric. I found a site that converts ingredients from metric to customary measurements. The main question I have is about the butter measurement. The recipe calls for 100 grams of butter. When I converted it to customary measurements it was 7 tablespoons. To make for easier measuring, can I increase this by a tablespoon to make it 8 tablespoons? Will increasing the amount of butter by such a small amount have major impact on the outcome of the finished cookie (will it majorly affect texture, etc.) or by increasing it by such a small amount, will there not be any noticeable changes in the finished cookie?
