Understanding the ISI Whipped Cream Dispenser
An ISI whipped cream dispenser is a culinary tool that uses nitrous oxide cartridges to create light and airy whipped cream or foams. It consists of a metal canister with a nozzle and a plunger that forces the mixture through the nozzle. When using tomatoes in an ISI dispenser, the goal is to create a smooth, velvety foam with a balanced flavor and texture.
Key Considerations for Choosing the Best Tomato for ISI
1. Acidity: Tomatoes with higher acidity levels produce foams that are more stable and have a brighter flavor. Look for varieties with an acidity level of at least 0.5%.
2. Sugar Content: Tomatoes with lower sugar content create foams that are less dense and have a more delicate flavor. Aim for varieties with a Brix level (a measure of sugar content) of around 5-7%.
3. Texture: Firm tomatoes with a low water content produce foams that are more consistent and have a less grainy texture. Avoid tomatoes that are overripe or have a mealy texture.
4. Flavor: Choose tomatoes that have a well-balanced flavor profile, with a combination of sweetness, acidity, and umami. Avoid tomatoes that are bland or have an overpowering flavor.
