Fond
Fond is the layer of browned, caramelized bits that sticks to the bottom of a pan after you sear meat, poultry, fish or vegetables. The word is French for "base" or "foundation", and that is exactly what it becomes: the flavour base for pan sauces, gravies, stews and braises.
What fond is made of
When protein and sugar-rich juices leak out of food in a hot pan, the water evaporates and the solids stick to the metal. There they brown through the Maillard reaction and some caramelization, concentrating savoury, roasted flavour.
Fond contains:
- Browned proteins and amino acids (deep savoury flavour).
- Caramelized sugars (sweetness and colour).
- Rendered fat and gelatin (body and richness).
How to build good fond
- Use the right pan. Stainless steel or cast iron. Nonstick barely makes any.
- Pat food dry. Moisture steams rather than browns.
- Preheat properly. Medium-high heat, with oil just shimmering, roughly 180–200 °C / 355–390 °F at the pan surface.
- Don't crowd. Leave a finger's width between pieces so steam can escape.
- Leave it alone. Moving food constantly prevents a crust and the fond that comes with it.
Fond vs burnt
Watch the colour. Golden to mahogany is fond. Black is burnt. If the bottom of the pan is darkening too fast, lower the heat or add a splash of water to loosen it early.
Chef Fizz says: Those "dirty" bits in your pan are the tastiest thing in the kitchen. Never wash flavour down the drain!
Using fond
The fond is released by deglazing: pour in a cold or room-temperature liquid and scrape with a wooden spoon. The liquid dissolves the browned bits almost instantly.
From there you can:
- Reduce it with stock and finish with butter for a pan sauce.
- Add flour for gravy.
- Return seared meat and add more liquid to braise.
Quick numbers
For a 25–30 cm (10–12 in) skillet after searing two to four portions of meat, about 120 ml (½ cup) wine or stock is enough to deglaze. Reduce by half, add another 120–180 ml stock, reduce again, and swirl in 15–30 g (1–2 tbsp) cold butter.
Questions
How do you tell fond from burnt bits?
Good fond is golden to deep brown and smells roasted. If it is black and smells acrid, it has burned and will make the sauce bitter, so wipe the pan and start again.
Can you make fond in a nonstick pan?
Not much. Nonstick surfaces are designed to stop food sticking, so little residue forms. Stainless steel, cast iron and carbon steel make the best fond.
What liquid do you use to deglaze fond?
Wine, stock, water, beer, cider, vinegar or juice all work. Use roughly 120–250 ml (½–1 cup) for a typical 25–30 cm skillet.
Does fond add salt to a sauce?
It can. Fond is concentrated, including any salt from seasoning, so taste the finished sauce before adding more salt.
