Mashed Potato Spice Blend

Mashed Potato Spice. Roasted onions, smoked salt, and blue fenugreek for the humble potato.

The Mashed Potato Spice is a spice blend with roasted onions, smoked salt, and blue fenugreek, which Ingo Holland developed together with Tim Mälzer for potato dishes. Not a neutral potato salt, no instant mash, no universal seasoning shaker.

The Mashed Potato Spice is a spice blend from Altes Gewürzamt that transforms mash, baked potatoes, and potato soup into a dish in its own right. Mashed potatoes, perhaps the simplest dish in German cuisine, have received their own special blend here. If you think that's excessive, you haven't experienced what roasted onions, smoked salt, and a dozen spices can do to a crushed potato. The side dish, which usually tastes of butter and little else, becomes a plate with depth, warmth, and a fine smoky note. The blend was developed by a Michelin-starred chef and inspired by a celebrity chef who takes potatoes more seriously than his reputation suggests.

Smoke, Roasted Onion, and a Hint of Alpine Cheese

The blend tastes warm, hearty, and slightly smoky, with sweet roasted onions in the foreground and a spicy cheese note on the finish. This note comes from blue fenugreek, an ancient alpine spice that gives Swiss herb cheese its aroma and builds a bridge to the potato here. Caraway and coriander provide a familiar, almost bready seasoning. Mace, the finely ground aril of nutmeg, enhances the earthiness of the tuber without overpowering it. The smoked salt drapes a hint of campfire over everything. Allspice and pepper add a subtle, warming spiciness in the background, which never makes the mash hot, but saves it from monotony. Together, this creates an aroma reminiscent of hearty pub cuisine, composed more precisely than it would ever be served there.

The smoky note is present but not dominant. However, those who appreciate a purist purée à la française, with only butter, milk, and nutmeg, will find the blend too rustic. It is made for robust, hearty potato cuisine, not for fine gastronomic silk.

In the tin, the blend appears coarse and varied, with visible onion pieces, whole seeds, and dark salt flakes. Upon opening, the scent of roasted onions rises first, then the smoke, and finally a faint caraway note. This triad alone reveals where the journey leads: into hearty, warming cuisine, not delicate artistry.

Mash is Just the Beginning

The blend seasons everything made from potatoes, from mash to fried potatoes to soup. For classic mash, cook predominantly waxy potatoes in salted water, add butter or olive oil, and roughly crush everything with a fork. Then sprinkle half a teaspoon of the spice blend over it, fold it in, let it steep briefly, then taste. Brush baked potatoes with oil and a pinch of the blend before baking. In potato soup, a teaspoon replaces the usual smoked bacon foundation, making it interesting for vegetarian cuisine too. Fried potatoes get their seasoning in the last minute, along with a knob of butter.

The choice of potato variety determines the texture. Predominantly waxy varieties like Laura or Belana yield a chunky mash with bite, to which the coarse spice pieces adhere. Floury varieties disintegrate more finely, absorbing the seasoning more evenly, resulting in a creamier and milder outcome. For the full effect of the blend, we recommend the chunky version. Another recipe idea: Foam up brown butter, stir in half a teaspoon of the seasoning, and drizzle it over the finished mash. The nuttiness of the butter significantly enhances the roasted onion note.

Beyond potatoes, the principle also works: sweet potatoes, pumpkin purée, and parsnips all tolerate the smoky roasted onion note equally well. For fries and wedges, you might prefer the Seasoning Salt for Fried Foods from the same manufacturer, and for vegetable stir-fries, the Vegetable Seasoning.

Good to know: The blend already contains salt, including smoked salt. Be careful when re-salting; taste at the very end. Used sparingly, the tin will last for many weeks, because without anti-caking agents, the preparation is more concentrated than commercial shakers. Store it in a dark, dry place, and the roasted onions will remain crispy and the aroma stable for months. Sprinkled directly over a steaming pot, however, the blend will absorb moisture and clump over time. It's better to use a dry spoon to take it out.

Two Chefs, One Tuber

The Mashed Potato Spice was created in collaboration between Ingo Holland and Tim Mälzer, two chefs who could not be more different. Here, the Franconian Michelin-starred chef who ran his restaurant with a Michelin star and 18 Gault-Millau points before dedicating himself entirely to his spice manufactory in Klingenberg in 2007. There, the Hamburg celebrity chef who has made honest everyday cooking his brand. Both met over the potato, a product that is on the table daily in German kitchens and yet rarely taken seriously.

The blend bears the signature of both. From Mälzer comes the uncomplicated demand that a dish should be improved without effort. From Holland comes the precision in the composition; each of the ten or so ingredients has a purpose. Roasted onions bring sweetness, smoked salt brings depth, blue fenugreek brings recognizability. Since Holland's death in 2022, his son Kilian has continued the manufactory on the Main. We have been stocking the Klingenberg spices since 2009 and have had mash with this blend on our table more often than we'd like to admit.

The blue fenugreek, in particular, deserves a second look. This inconspicuous herb, also known as bread clover, has grown in the Alpine region for centuries, where it seasons cheese and farmer's bread. In South Tyrol, it's an ingredient in Vinschgerl bread, and in Switzerland, in green Ziger cheese. That it gives a potato blend its distinctive character is an idea that you only understand once you've tasted both together. It was precisely such cross-connections that made Holland a sought-after spice developer for colleagues in top gastronomy.

From Side Dish to Main Star

What distinguishes this spice preparation from other potato seasonings is its direction. Most products in this category are salt blends with a little paprika, intended as a sprinkler seasoning over the finished dish. Here, however, a composition was developed for a specific dish, with roasted onions as the core flavor carrier instead of an alibi ingredient. As a gift for a rustic dinner, the tin makes more of an impression than a bottle of wine. If you want to delight a potato lover, you're rarely wrong here. A gift with a built-in recipe, as the preparation is clearly stated in three sentences. The blend also proves its worth at a barbecue buffet, sprinkled over foil-wrapped potatoes, alongside quark and herb butter. There, it incidentally answers the question of why the potatoes were so good this time.

Bring the mash back to the center of the plate, where it belongs with this seasoning.
