Part of the Prep and Production Cook track. Lesson 8 of 10.
Where in the shift: and re-checked through it.
Prerequisites: Modules 12, 16, 39.
The sequence
Hydrate to the press test.
Cover the working dough.
Take only what the bench needs.
Re-test every hour or two.
And taste one toasted chile alone before it goes in the batch.
The decisions
Whether the dough is in its window. Not once — repeatedly, because masa loses water continuously to a warm kitchen and the dough correct at ten is under-hydrated by two.
How long to toast chiles. Seconds, and the window is one to two seconds wide at the end.
And whether a toasted batch is usable. This is the decision that saves whole batches. A single over-toasted chile embitters an entire batch of sauce and nothing masks it, per Module 39.
What you are reading
The press test. A smooth round with clean unfractured edges.
Almost-right: faint hairline fractures at the very edge. Still workable and it will stop puffing within the hour — that margin is the earliest signal available.
And the chile's aroma. The toasted sweetness picking up an edge is the last warning.
What goes wrong here
Masa drifted dry. Cracking edges, no puff, tortillas breaking on the fold.
Chiles scorched. Bitter, acrid batch with no possible correction.
And pressed ahead for a surge — tortillas pressed twenty minutes early dry at the edges and crack on the fold. Stage the masa, not the pressed rounds.
Verification
Press and cook one before every service push. That is the check and it takes ninety seconds.
And taste one chile from every toasted batch. Five seconds.
The boundary
In-house nixtamalization involves an alkaline process with handling requirements, and masa production, holding, and shelf life are governed by the local health authority.
