How to Use Up Any Amount of Mustard

September 27, 2016

Mustard is one of those fridge-door features that essentially becomes a part of the landscape: It almost feels like the jar will never, ever run out, like there might be some secret mustard spring very gradually replenishing it.

When you finally have just a modest slick of it left on the walls of the jar (or if you're just trying to hit the bottom), don't let it go to waste. Even a little bit of mustard provides round, spicy punchiness to whatever it's added to. Here are a few ideas for how to use it:

  • Make a vinaigrette directly in the mustard jar: Drizzle in oil, salt and pepper, a bit of honey, and shake like the Dickens—then pour over your salad.
  • Mash mustard into softened butter, refrigerate until firm, and then use as a compound butter. It would be killer on steak. Or on an egg sandwich, or smoked salmon toasts.
  • Toss just-roasted vegetables with mustard (thinned with a little olive oil) so that they absorb it while they cool. Brussels sprouts and broccoli especially love this treatment.
  • Combine shredded cheese with mayonnaise and mustard for a melty spread for cheese toasts and grilled cheese. (Or biscuit sandwiches.)
  • Make a mustardy sauce for mussels! This recipe sounds spiffy, and only takes about 20 minutes.
  • Add it to meat marinades.
  • Or spread mustard onto slices of tofu before pan-frying. (This is especially good with whole-grain mustard.)
  • Fold it into leftover cooked potatoes and cabbage and pan-fry it for a zipper version of bubble and squeak.
  • It's just as good in potato salad.
  • Add honey and you've got a quick honey mustard for dipping (or glazing chicken wings).

I recently spread mustard over a pork tenderloin, rolled it it chopped sage and rosemary, seared it on all sides, transferred to a baking dish, roasted for 20 mins and served it thinly sliced and drizzled with the reduced juices and balsamic vinegar on a bed of rocket! Phew!

My mustard loving husband tends to abandon the old one(s) when a new one appears. I periodically consolidate the orphans and use it in most of the ways given.

This article is perfection. I live down the street from the National Mustard Museum and could definitely be classified as a mustard hoarder.... <br />I hoard bacon fat too and it's piling up quickly. I use it for frying the occasional hash and apple cider caramels in the fall. I'd love to hear how everybody else likes to use their bacon fat! Esp. non-baking applications.

Kill two birds with one stone: Stir into the equally forlorn leftover spoonfuls of jam hogging valuable real estate in your fridge, and spread on grilled ham or turkey and cheese, or not-grilled for that matter. <br />Stir into split pea soup just before serving: take a ladle of soup out, stir the mustard into it, and then stir that back in.<br />Or, stir the mustard into sour cream or Greek yogurt, and stir that into split pea soup, or carrot soup, to brighten either up.<br />Or, stir into any kind of jam, add a splash of soy sauce and a splash of wine or lemon juice + some fresh herbs if you like, to glaze anything grilled.<br />Or, stir into pan sauces of a roast chicken or pork tenderloin with a splash of stock or wine.<br /><br />Or put it in this sauce: https://food52.com/recipes/30915-herbed-feta-and-steak-sandwich<br /><br />I could go on, but I'll stop here, to avoid the rude, snarky criticism to which I've been subjected on Food52 when posting detailed, informative answers intended only to be helpful. ;o)

antonia, your suggestion about split pea soup is interesting but why take out the ladle of soup, stir in the mustard and put it back? Why couldn't you just add a little directly to the soup and stir it in well?
 
AntoniaJames April 21, 2016
It blends into the soup better that way. Of course, you can also stir in a small amount to each bowl and let people stir it in themselves. This works better if stirring the mustard into yogurt or cream before dolloping on. ;o)

Forget those bad apple comments; you always have great ideas, Antonia! It's obvious that the community here holds you in high regard. The mere thought of that glaze has me salivating....

These are all great ideas, but I never have the problem of an old jar that needs to be used up. I regularly go through a jar or two a month. :)
