Answer: REAL FOOD

All ingredients start with either a B or a W. If the quantities for each ingredient are converted to tablespoons (as the portion size for the Preparatory Steps suggests), then each recipe converts to a string of B and W. The ingredients of the Preparatory Steps thereby serve as a shorthand for longer strings of B and W.

Decoding the main recipe works exactly the same way, only it leads to much longer strings. The lengths of the strings are all multiples of 5:

100 = 20 x 5 160 = 32 x 5 85 = 17 x 5 95 = 19 x 5 185 = 37 x 5 165 = 33 x 5 110 = 22 x 5 135 = 27 x 5

These are the same as the number of little squares for each of the eight rectangle shapes in the serving suggestion.

Writing each string of B and W in 5 lines (as the serving suggestion hints) gives the following result:

BWBWBWBWBBWBBWBWWBBW
BWBWBWBWBWWBWWBWWBWW
BWBWBBBWBBWBBWBWWBBW

Each string contains an encoded word that becomes clearly visible when treating the B as black pixels and the W as white pixels:

█ █ █ █ ██ ██ █ ██

Each word is the English translation of an Italian pasta type:

RUOTE
ELICOIDALE
ANELLI
LUMACHE
FARFALLE
ORECCHIETTE
ORZO
DITALI

Taking the first letter of each word yields REAL FOOD, the solution.
