New Product Tin Fish Sauce

The scoop

If you’ve been wanting to explore authentic Asian cooking at home, Costco just made it a whole lot easier. The Muac Mam Tin Fish Sauce is now on shelves, and it’s the real deal for anyone serious about Vietnamese, Thai, or Filipino cuisine. It’s been produced since 1693 (no, that’s not a typo!).

This isn’t some watered-down version – it’s proper, authentic fish sauce with that distinctive umami punch you need for pho, pad thai, spring rolls, and countless other dishes. The bottle is a generous size that’ll last through many cooking sessions, which is exactly what we expect from Costco.

The quality here is solid. Fish sauce can vary wildly between brands, but this one delivers that essential savory depth without being overwhelmingly pungent. Yes, it still smells strong when you first open it (that’s fish sauce for you), but it mellows beautifully when cooked and adds incredible complexity to your dishes.

Bottom Line: If you regularly cook Asian food or want to start, this is a pantry essential worth grabbing. The value is there, and you’ll actually use it all before it goes bad—just store it in the fridge after opening to maintain freshness.
