You know sweet, salty, bitter and sour. Now school your taste buds in the fifth taste, umami, the savory effect in Umami Ketchup.

Its umami power comes from a label full of ingredients: tomatoes, spices, oyster extract, truffle oil, dashi powder, etc.

Tasters found it a tad sweet, but liked its full-bodied, barbecue-like flavor. The 14.5-ounce bottle is $7.50 at www.umami.com.
