Someone has murdered professor Taste. We think it was you, with bland condiments, in the kitchen.Let us clue you in to Tin Mustard.Made in Brooklyn, the mysteriously delicious spread is the work of Slovenian-born chef Tin Dizdarevic. He uses only whole grain mustard and never grinds the seeds, which gives the delicacy a caviaresque texture. He keeps production under 200 jars per batch, and even those with dietary restrictions can enjoy without guilt.Choose your weapon wisely: knife (spread on toast with your favorite fixings), fork (right out of the jar, no judgments), or spoon (globbed onto steak or the world’s classiest hot dog). Dizdarevic is also happy to provide recipes if you ask (think summer tomato and roasted corn salad with mint).So whether you’re in the study, the billiard room, or the ballroom, pick Tin’s whole kernel mustard for your next sandwich.It’ll be killer.Available at Smorgasburg, 27 North 6th Street, at Kent Avenue, Williamsburg (brooklynflea.com); online at tinmustard.com, $7.
