Tomato and orange: an egg-free emulsion inspired by Massimo Viglietti

Tomato, orange and extra virgin olive oil can form a fresh sauce with enough body for dots or an accompaniment. Inspired by chef Massimo Viglietti’s work, this proposal explores the technical principle without claiming to be his official recipe.

The role of xanthan

Xanthan increases water-phase viscosity and can help stabilise the sauce. It does not automatically replace every emulsifier or allow unlimited oil incorporation without testing.

Tomato and orange juice vary considerably in water, pulp and acidity. Weigh both for a repeatable trial, strain for a smooth sauce and record the chosen ratio.

How to plan a trial

Blend tomato and juice until homogeneous. Add a small, weighed quantity of xanthan while mixing, allow hydration and check texture. Then incorporate oil gradually while continuing to blend.

One tomato and one orange do not represent a constant weight: a gum dose in grams requires a weighed base. Start with a measured sample and adjust in small increments.

Taste before dispensing

Adjust salt, acidity and oil in the finished preparation. An overly thick sauce can hide the orange’s freshness and feel sticky. Check again after resting.

For weighing, read the cold-use xanthan guide; for alternatives, compare Ultratex and agar agar.
