Magnifisauce! — Trader Joe's famous 'special sauce': a mustard-mayo-ketchup-relish blend for burgers and beyond.
About This Product
Trader Joe's describes Magnifisauce as 'a tangy sauce of secret proportions' — their homage to the classic American burger-stand special sauce. It's a mustard-mayo-ketchup-relish kind of blend: creamy and tangy with real pickle-relish chunks and a warm spice finish.
One squeeze turns a home burger into a drive-thru burger. It moonlights as fry dip, sandwich spread, and salad dressing.
How to Enjoy
- On smash burgers and cheeseburgers
- Fry and onion-ring dip
- In roast beef or chicken sandwiches
- As Reuben-style dressing
- Thinned with vinegar for a salad dressing
This one's a good fit if
- Home burger-night regulars
- Fans of that fast-food 'special sauce' taste
- Fry-and-dip devotees
- US drive-thru flavor nostalgics
Why Korean Customers Reach for This
The 'special sauce' category barely exists on Korean shelves — you make it yourself or go without. Magnifisauce bottles the taste US burger culture is built on, and it's one of TJ's most re-purchased condiments.
