Hot mustard butter is a bold, intensely mustardy compound butter made for breakfast sandwiches that need a serious flavor boost. Sharp, tangy, savory, and pleasantly hot, it melts into warm eggs, sausage, bacon, biscuits, English muffins, and toast for a breakfast bite that refuses to be bland.

Featured Standouts

Mustard Powder

Mustard powder delivers an intense, sharp mustard punch with a lingering heat that cuts through rich breakfast meats, eggs, and cheese.

Butter

Rich and creamy, butter carries the concentrated mustard flavor while giving it a smooth, spreadable texture.

Cold Water

Cold water activates the mustard powder, helping unlock its strongest sharp and spicy characteristics.

Salt

Salt sharpens the savory flavor and keeps the mustard from tasting flat.

TIPS & TRICKS FOR THE BEST HOT MUSTARD BUTTER

Let the mustard bloom

Mix the mustard powder with cold water before adding it to the butter. This activates the mustard and brings out its characteristic heat and sharpness.

Do not underestimate the mustard

This is intentionally an intense mustard butter. The goal is not a subtle background flavor. A small amount should be noticeable against eggs, cheese, and breakfast meats.

Spread it on warm bread

Apply the butter while your biscuit, English muffin, toast, or bread is warm. The heat helps the butter melt into the bread and distribute the mustard flavor. I love frying sandwiches in this butter for a really heavy punch. 

Pair it with rich ingredients

This butter shines alongside bacon, sausage, eggs, cheese, and other rich breakfast ingredients. The mustard cuts through that richness and keeps the sandwich from tasting heavy.

Give it time to develop

Let the mustard mixture sit briefly after combining it with the water before mixing it into the butter. This gives the mustard flavor time to develop.

Inclusive Adaptions

For sensory sensitivities

Start with a thinner layer of butter on the sandwich and increase the amount as the mustard intensity becomes comfortable.

For limited hand strength

Use softened butter and a hand mixer or stand mixer to fully incorporate the mustard mixture.

For dairy sensitivity

Use a dairy-free butter alternative with a neutral flavor so the mustard remains the dominant flavor.
