Tomato ponzu
A surprising variation on ponzu. Tomatoes are full of umami and also contain acidity, making them ideal as a base for ponzu. The infusion programme in the vacuum machine allows you to infuse liquids cold. This also preserves the volatile flavour compounds that would otherwise evaporate when heated.
In this component, we use the Henkelman vacuum sealer. With this professional chamber vacuum sealer, you can pack, store, and prepare food more efficiently.
