Environmental Benefits
Lupin beans are a sustainable crop, requiring less water and pesticides compared to other legumes. By choosing lupin flour, you’re supporting environmentally friendly agriculture and reducing your carbon footprint.
Equipment and Ingredients Needed
To make lupin flour at home, you’ll need the following equipment and ingredients:
Equipment
- A grain mill or high-speed blender
- A food dehydrator or oven
- A fine-mesh sieve or sifter
- A storage container for the flour
Ingredients
- 1 cup of dried lupin beans
- Water for soaking and rinsing
The Process of Making Lupin Flour
Making lupin flour at home involves several steps, from soaking and dehydrating the lupin beans to grinding and sifting the flour.
Step 1: Soaking and Rinsing
Rinse the dried lupin beans and soak them in water for at least 8 hours or overnight. This will help to rehydrate the beans and make them easier to grind.
Step 2: Dehydrating
Drain and rinse the soaked lupin beans, then spread them out in a single layer on a baking sheet or dehydrator tray. Dehydrate the beans at 135°F (57°C) for 6-8 hours or until they’re dry and brittle. You can also use your oven on the lowest temperature setting with the door slightly ajar.
Step 3: Grinding
Once the lupin beans are dehydrated, allow them to cool completely. Then, transfer them to a grain mill or high-speed blender and grind them into a fine flour. You may need to grind the beans in batches depending on the size of your equipment.
Step 4: Sifting
Transfer the ground lupin flour to a fine-mesh sieve or sifter and sift it to remove any large particles or debris. This will help to create a smooth and even texture.
Tips and Variations
To get the most out of your homemade lupin flour, here are some tips and variations to consider:
Roasting the Lupin Beans
Roasting the lupin beans before grinding them can enhance the flavor and aroma of the flour. Simply spread the dehydrated lupin beans out in a single layer on a baking sheet and roast them in a 350°F (180°C) oven for 10-15 minutes or until fragrant.
Adding Flavorings
You can add flavorings such as herbs, spices, or nuts to the lupin flour to create unique and delicious flavor profiles. Simply mix the flavorings into the flour after it’s been sifted.
Using Lupin Flour in Baking
Lupin flour can be used as a 1:1 substitute for wheat flour in many recipes. However, keep in mind that lupin flour can be denser and heavier than traditional flours, so you may need to adjust the liquid content and leavening agents in your recipes.

You will also need a bowl or container to store the flour in. If you want to dry the lupin beans before grinding them, you will also need a dehydrator or oven.
It’s worth noting that you don’t need to have a high-powered blender or grinder to make lupin flour, but having one can make the process easier and faster. Additionally, if you plan on making large quantities of lupin flour, you may want to invest in a more heavy-duty grinder or mill.
How do I prepare the lupin beans for grinding?
To prepare the lupin beans for grinding, you will need to soak them in water for at least 8 hours or overnight. This will help to rehydrate the beans and make them easier to grind. After soaking, drain and rinse the beans, and then dry them thoroughly with a clean towel or paper towels.
If you want to dry the lupin beans further, you can place them in a dehydrator or oven on the lowest heat setting for a few hours. This will help to remove any excess moisture and make the beans easier to grind. However, be careful not to over-dry the beans, as this can make them difficult to grind.
How do I grind the lupin beans into flour?
To grind the lupin beans into flour, simply place them in a blender or food processor and process until they are finely ground. You may need to stop the blender and scrape down the sides a few times to make sure everything gets ground evenly. Alternatively, you can use a coffee grinder or spice grinder to grind the beans into flour.
It’s worth noting that grinding lupin beans can be a bit tricky, as they can be quite hard and dense. However, with a little patience and persistence, you should be able to get a fine, smooth flour. If you find that your flour is not fine enough, you can try sifting it through a fine-mesh strainer or sifter to remove any lumps or large particles.
How do I store lupin flour to preserve its nutritional value?
To store lupin flour and preserve its nutritional value, it’s best to keep it in an airtight container in the refrigerator or freezer. This will help to keep the flour fresh and prevent it from becoming rancid or developing off-flavors.
When storing lupin flour, make sure to keep it away from light and heat, as these can cause the flour to degrade over time. You can also store lupin flour in the pantry, but it’s best to use it within a few weeks to ensure optimal freshness and nutritional value.

When substituting lupin flour for wheat flour, start by using a small amount and adjusting to taste. You may also need to add xanthan gum or guar gum to help with texture and structure, as lupin flour can be quite dense and heavy. Additionally, keep in mind that lupin flour has a stronger flavor than wheat flour, so you may need to adjust the amount of liquid or seasonings in the recipe.
