Start by sifting the dry ingredients in a bowl. Simply place on top, a sieve that fits the mixing bowl perfectly. Next add the dry ingredients one by one and then start sifting. To speed up the process tap the sieve continuously while slowly shaking it. Once done, discard any left over big particles (try pushing them down using a spoon first, as sometimes they form big lumps due to exposure of moisture. Thus pushing them down make help lower the waste). Mix all the sifted dry ingredients and move on to the next step.
