This recipe combines the creamy texture of potatoes with the tangy flavor of mustard and the vibrant green goodness of spinach. It's a perfect side dish that pairs well with a variety of main courses, from grilled meats to vegetarian options.

Instructions:

1. Prepare the Potatoes:
- Peel the potatoes and cut them into evenly sized chunks. This ensures they cook evenly.
2. Cook the Potatoes:
- Place the potato chunks in a large pot and cover them with cold water.
- Add a pinch of salt to the water to enhance the flavor.
- Bring the water to a boil over high heat. Once boiling, reduce the heat to medium and let the potatoes simmer for about 15-20 minutes, or until they are tender when pierced with a fork.
3. Prepare the Spinach:
- While the potatoes are cooking, wash the spinach leaves thoroughly and pat them dry.
- Roughly chop the spinach.
4. Heat the Milk:
- In a small saucepan, gently heat the milk over low heat until it is warm, but not boiling. This will make it easier to incorporate into the potatoes later.
5. Mash the Potatoes:
- Once the potatoes are tender, drain them well in a colander.
- Return the drained potatoes to the pot or place them in a large mixing bowl.
- Use a potato masher or a fork to mash the potatoes until smooth.
6. Mix in the Mustard and Spinach:
- Add the 1 tablespoon of mustard to the mashed potatoes and mix well to combine.
- Stir in the warm milk a little at a time, mashing as you go, until you reach your desired consistency.
- Fold in the chopped spinach. The residual heat from the potatoes will wilt the spinach nicely as you mix it in.
7. Season and Serve:
- Taste the mash and season with salt and pepper to your preference.
- Serve the Seeded Mustard and Spinach Potato Mash hot as a delicious side dish for any meal.

Seeded mustard and spinach potato mash FAQ:

What is the best way to know when the potatoes are done cooking?

The potatoes are done when they are tender and easily pierced with a fork, usually after 15-20 minutes of simmering. Ensure all pieces are uniform in size for even cooking.

Can I use a different type of milk in this recipe?

Yes, you can substitute the 1% milk with any milk you prefer, such as whole milk, almond milk, or oat milk. Adjust the amount according to your desired creaminess.

How should I store leftovers of the potato mash?

Store any leftover potato mash in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of milk if it thickens.

What can I use instead of mustard if I don’t have any?

If you don't have mustard, you can substitute with a bit of mayonnaise or skip it altogether for a simpler flavor. You may also consider adding other seasonings like garlic or herbs.

What size pot is best for boiling the potatoes?

A large pot is recommended to allow enough space for the potatoes to be fully submerged in water, helping them cook evenly. A pot holding at least 4-6 quarts is suitable.

Tips:

- Ensure the potatoes are cut into evenly sized pieces for uniform cooking.

- Boil the potatoes until they are very tender; this makes mashing easier and results in a smoother texture.

- For a richer flavor, you can use whole milk instead of 1% fat milk.

- Wilt the spinach in the microwave or on the stovetop before adding it to the mash to avoid excessive liquid.

- Mix in the mustard gradually and taste as you go to adjust to your preferred level of tanginess.
