How to Seal Food without a Vacuum Sealer
Hi, I'm Kenji Lopez-Alt, and I am going to show you a method for how to seal food airtight without using a vacuum sealer. It's a method called the water displacement method, and it's really great for if you're gonna freeze food, store food in the fridge, or if you're gonna cook sous vide.
嗨，我是 Kenji Lopez-Alt，我要帶你們看一個不需真空保鮮機就能將食物密封的方法。這是種叫作排水法的作法，非常適合用在如果你要冷凍食物、儲藏食物在冰箱，或如果你要用真空低溫烹調法時。
Now, what you do is you start by putting your food in a plastic bag—this is some beef chuck—then you seal the plastic bag almost all the way, leaving just about an inch open. Next, you take a tub or a pot of water and you gently lower the food down into it. Now, as the food goes down, the water pressure is gonna push all of the air out of that bag. You wanna keep going down until just that little corner of the bag that you left open is about to be submerged. And just before it goes underwater, you seal it off. And there we have food that is stored in a completely air-free bag with no vacuum sealer.
- 「完全、全部」- All The Way
