8. User Tips
- Preheat Water: For faster cooking, you can start with warm tap water, but ensure it's not too hot to avoid exceeding the desired temperature before the device stabilizes.
- Use a Lid: Covering your cooking container with a lid or plastic wrap can significantly reduce heat loss and evaporation, especially for longer cooking times.
- Submerge Completely: Always ensure your vacuum-sealed food bag is fully submerged in the water. If it floats, use a heavy object (like a ceramic plate) to weigh it down.
- Searing for Flavor: For meats like steak, a quick sear in a very hot pan after sous vide cooking will create a delicious, flavorful crust without overcooking the interior.
- Experiment with Recipes: Don't be afraid to try different temperatures and times for various ingredients. The app (WIFI version) often provides a good starting point for many recipes.
