Questions from the pass

Modernist Cuisine: frequently asked

Why does my agar gel split when I blend it?

Agar fluid gels split if the agar concentration is too low or the shear rate is insufficient. Use a 1% to 1.5% agar-agar ratio by weight to the liquid. Boil for three minutes to hydrate fully, set completely in the fridge, then blend at high speed in a Vita-Prep until completely smooth, adding 0.1% xanthan gum to stabilise.

What temperature and time for sous vide beef short ribs?

For a steak-like texture, cook short ribs at 57°C for 72 hours. For a traditional, flakey braised texture that still retains moisture, cook them at 62°C for 48 hours. Always salt the meat lightly beforehand and chill rapidly in an ice bath if not serving immediately to prevent bacterial growth.

Why is my soy lecithin foam collapsing on the plate?

Soy lecithin foams fail when the liquid is too thick, too fat-heavy, or not aerated at the correct temperature. Keep the liquid warm (around 50°C to 60°C) and use a ratio of 0.5% to 1% soy lecithin powder by weight. Use a wide, flat container and aerate with a hand blender held at an angle to pull in air.

How do you clarify tomato juice with a centrifuge?

To get crystal-clear tomato water for consommés, spin pureed tomatoes in a benchtop centrifuge at 4,000 RPM for 20 minutes. The high G-force separates the dense insoluble solids from the clear liquid without heat, preserving the fresh, raw tomato aroma. Add 0.1% pectinase beforehand to break down pectin and increase the yield.

Why are my sodium alginate spheres chewy and tough?

Tough skin on spheres happens when they sit in the calcium bath too long or the calcium chloride concentration is too high. For direct spherification, use a 0.5% sodium alginate bath and a 1% calcium lactate gluconate solution for the flavour base. Rinse the spheres in clean water immediately after one minute of curing.
