How to Balance Acidity in Sauces
Balancing acidity requires working in the opposite direction of the sour note. If a sauce is too sharp, you counteract it by introducing fat to coat the palate, adding a touch of sweetness to dull the edge, or increasing the salt to shift the flavor profile. If the sauce remains stubbornly tart, you must dilute the acid with more base ingredients like stock or cream to drop the concentration.
Taste as you build, not just at the end.
Keep a clean spoon handy for constant tasting. Adjusting acid is a game of millimeters; add small amounts and stir thoroughly before assessing again.

Fat first, then salt, then sweet
Always start with fat to round out the sharpness. Only move to sweetness if the sauce feels thin or one-dimensional after the fat has been incorporated.
The method.
Assess the sauce
Determine if the sharpness is masking other flavors or if it is simply overpowering the mouthfeel.
Incorporate fat
Whisk in a tablespoon of cold butter or a splash of cream. This binds with the acid and softens the bite on your tongue.
Adjust salinity
Add a small pinch of salt. Salt tricks the brain into perceiving less sourness and brings out the savory depth of your sauce base.
Introduce a touch of sweetness
Use a drop of honey or sugar if the sauce feels 'stuck' in the acidic range. It balances the profile without necessarily making the dish dessert-like.
Dilute as a last resort
If the sauce is heavily oversaturated with vinegar or lemon, whisk in a bit more un-acidified stock to drop the overall concentration of the acid.
When it doesn't go to plan.
Always warm the butter before adding it so it emulsifies into the sauce rather than leaving a greasy film.
Avoid using flavored sweeteners like molasses unless the sauce profile supports that level of complexity.
If using cream, temper it by adding a spoonful of hot sauce to the cream in a separate bowl before pouring the mixture back into the main pot to prevent curdling.

Can I use baking soda to neutralize acid?
It is technically possible, but it often leaves a metallic, soapy aftertaste and creates unwanted foam. It is rarely worth the risk to the flavor.
How do I know if I have added too much fat?
The sauce will lose its glossy look and begin to look matte or separated. If this happens, your only path forward is to dilute with more stock.
