Replace the job, then correct the side effects
For pasta, the page's working definition is: The sauce finishes on the pasta, not the other way around. Undercook it by a minute, move it into the pan with a ladle of its water, and let the starch pull the sauce onto it. The swap cards below are judged against that job rather than visual resemblance.
Job → candidate → side effects → small test → correct.
1 · Job
What is the missing ingredient doing?
2 · Candidate
Choose the shelf item that replaces that function.
3 · Side effects
Check water, fat, salt, acid, sweetness, and texture.
4 · Small test
Change a spoonful or small portion first when possible.
5 · Correct
Taste again and move only the axis that is still wrong.
