How to Fix grainy cheese sauce (Rescue in Minutes)
Dinner is on the line and something went sideways. Deep breath — this is fixable, usually in under five minutes.
The rescue, in order
- Off the heat, whisk in a splash of cold milk or a squeeze of lemon.
- Persistent grain: immersion-blend with a knob of butter.
- Next time: shred your own cheese (bagged anti-caking starch is the usual culprit), and melt it off the boil.
Why this works
Cheese proteins seize and squeeze out fat past ~160°F; acid and fresh fat coax them back into suspension.
So it never happens again
Pre-shredded cheese contains cellulose that fights smooth melting — the block cheese habit fixes half of all grainy sauces.
