Recipe for delicious pizza:

1. Make extra greasy pizza. Nauseating-level of grease.

2. Put pizza through De-Greasinator 5000.

Sounds efficient.

The grease is vaporised and inhaled by one randomly chosen Memphis resident, who permanently gets chronic asthma.

You only need to make the app once before running it on a million computers. So it's more like greasy flavor development, then de-greasinating the recipe before going into mass production. It's not a big efficiency impact overall, it's more about how you like to spend your flavor development time.
