How to Seal Food without a Vacuum Sealer
如何不用真空保鮮機就將食物密封起來
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.
現在,你要做的事是先將食物裝進塑膠袋--這是一些牛肩胛肉--接著你將塑膠袋幾乎完全封起,只要留大約一英吋的開口。接下來,拿一盆或一鍋水,輕輕將食物放進水中。現在,當食物向下時,水壓會將所有空氣推出塑膠袋。你要繼續往下放,直到你沒封上的那個小角快被浸到水裡為止。就在開口要進到水裡前,你將它封起來。然後我們就有保存在完全真空袋裡的食物囉,不需用到真空密封機。
- 「完全、全部」- All The Way
