Mumm's Sprouting Seeds Sandwich Booster is a sprout mix and sprouting seed blend for growing edible sprouts that bring crisp texture and a peppery, fresh flavor to everyday meals. It’s built around a balanced combination of mild leafy sprouts and bolder brassica bite, giving you a lively sprout profile without feeling overpowering.
This sprout mix features clover, alfalfa, radish, and mustard. The base of clover and alfalfa keeps the flavor mild and approachable, with a mild-sweet flavour and a mild nutty flavor that reads clean and fresh. The aroma stays light and green, like tender young leaves, setting up a smooth, easy-to-enjoy first impression.
Radish and mustard are what turn Sandwich Booster into a true “booster.” Radish sprouts are widely described as peppery, with a crisp, tender texture and a semi-sweet and peppery finish, while mustard sprouts are known for a sharp, spicy flavor that’s unmistakably mustard-like. Together, they bring a bright, zesty edge that wakes up the palate, giving the blend a more exciting bite than leafy sprouts alone.
Texture is one of the biggest reasons this sprouting seed blend is a staple. Clover and alfalfa contribute a light, leafy crunch that feels delicate and fresh, while the radish and mustard components reinforce that crisp, refreshing bite. The overall mouthfeel is clean and satisfying, with enough snap to feel substantial, yet still tender enough to stay easy to eat.
Beyond flavor and texture, this is an easy sprout blend designed to be straightforward and consistent. Mumm’s emphasizes in-house tested seed lots, with testing every lot in-house to support strong germination and cleanliness. That focus is especially helpful with a mixed blend like this, where you want dependable sprouting performance and a finished sprout mix that looks and tastes fresh.
Mumm's Sprouting Seeds Sandwich Booster is a good fit for anyone who wants a sprout mix that stays mild and leafy at the core, then finishes with a peppery lift from radish and mustard, with a crisp, tender texture that feels fresh in every bite.

Alfalfa is important because it supports steady growth momentum by feeding root-zone biology and providing natural plant-active compounds that encourage healthier roots and greener leaves, making it uniquely different from single-purpose inputs that only supply one nutrient or only target microbes.
