Spam musubi is a Hawaii-born snack of seared Spam and seasoned rice wrapped with a strip of nori, often shaped into a compact rectangle. This homemade version includes a simple nutrition estimate per piece, so you can see how the rice, meat, and glaze contribute while making a satisfying snack or lunch.
Ingredients
- 2 cups (370 g) short-grain white rice, uncooked
- 2 1/4 cups (530 ml) water, for cooking the rice; use the amount specified by your rice cooker if different
- 1/4 cup (60 ml) unseasoned rice vinegar
- 1 tablespoon (12 g) granulated sugar
- 1/2 teaspoon (3 g) fine salt
- 1 can (12 oz/340 g) Spam, cut crosswise into 8 slices
- 2 tablespoons (30 ml) soy sauce
- 1 tablespoon (15 ml) mirin
- 1 tablespoon (12 g) packed brown sugar
- 2 sheets (about 5 g) toasted nori, cut lengthwise into 8 strips
- 1 teaspoon (5 ml) neutral oil, such as canola, for the pan if needed
Instructions
- Rinse the rice in a bowl under cool water, changing the water several times until it is less cloudy. Drain well. Combine it with the measured water in a rice cooker and cook according to the machine’s directions. For a saucepan, bring it to a boil, cover, reduce the heat to low, and cook until the water is absorbed and the grains are tender, about 15 minutes; turn off the heat and let it stand covered for 10 minutes. The saucepan method adds standing time, so allow extra time if using it.
- While the rice cooks, stir together the rice vinegar, sugar, and salt until dissolved. When the rice is ready, transfer it to a wide bowl and gently fold in the vinegar mixture. Use a slicing motion rather than mashing the grains. Cover loosely with a clean towel while you cook the Spam; warm rice is easier to shape.
- Stir the soy sauce, mirin, and brown sugar together in a small bowl. Set a large skillet over medium heat. Add the Spam slices in a single layer, working in batches if necessary, and cook for 2 to 3 minutes per side until browned. Spam is a ready-to-eat product; this browning step is for texture and flavor, not a raw-meat safety cook. Pour in the sauce and turn the slices for about 1 minute, until glossy and lightly reduced. Remove from the heat.
- To shape the musubi, line the clean Spam can with a piece of plastic wrap, or use a musubi press. Spoon about 1/2 cup (90 g) seasoned rice into the mold and press firmly but gently into an even layer. Set one Spam slice on top, then lift out the stack using the wrap. Repeat to make 8 pieces. Avoid packing the rice so tightly that it turns gummy.
- Wrap a strip of nori around the center of each musubi, placing a dab of water on the end to help it adhere. Serve warm or at room temperature. For best texture, do not leave the musubi at room temperature for more than 2 hours.
Tips
- Use short-grain rice for the sticky, cohesive texture that holds its shape. Long-grain rice tends to crumble, so it is not a close substitute.
- For a less salty glaze, use low-sodium soy sauce and reduce it to 1 tablespoon (15 ml); the Spam itself is already seasoned. Tamari works in place of soy sauce, but check its label if gluten matters.
- If you do not have a musubi press, the empty, clean Spam can makes a convenient mold. Handle the cut can carefully, or use a dedicated press to avoid sharp edges.
- Keep the nori dry until wrapping and serve soon after assembly. Nori softens as it absorbs moisture from the rice, though it remains edible.
Serving Suggestions
Serve one musubi as a substantial snack or pack two with sliced cucumber, edamame, or a simple green salad for a light meal. Pickled vegetables add a bright, tart contrast to the savory glaze. For a lunchbox, keep the musubi chilled with an ice pack and let it come closer to room temperature before eating if you prefer softer rice.
Variations
For a spicy version, mix a little sriracha into the glaze or add a thin stripe of spicy mayonnaise just before wrapping. A sprinkle of furikake over the rice adds seaweed and sesame flavor; use a small amount because some blends are salty. You can also replace the mirin with 1 tablespoon (15 ml) water plus 1 teaspoon (4 g) sugar, though the sauce will lose mirin’s gentle sweetness and aroma. For a vegetarian alternative, use a plant-based luncheon slice and follow its package directions; flavor and nutrition will vary by product.
Storage and Reheating
Rice and musubi should be refrigerated within 2 hours of cooking or assembly; do not leave them out overnight. Wrap individual pieces or place them in an airtight container and refrigerate for up to 3 to 4 days. The rice firms when cold, and refrigeration can change its texture, so these are best eaten fresh. For longer storage, wrap tightly and freeze for up to 1 month for best quality; thaw in the refrigerator.
To reheat, remove the nori if you want to keep it crisp. Microwave a refrigerated musubi loosely covered for about 30 to 60 seconds, checking in short intervals, until hot throughout; add a few seconds as needed for a larger or colder piece. USDA FSIS guidance is to reheat leftovers to 165°F (74°C), checked with a food thermometer. Rewrap with nori after heating. Do not repeatedly warm and cool the same portion.
Frequently Asked Questions
What are the nutrition facts for one Spam musubi?
For this recipe, one of 8 pieces is estimated at about 300 calories, 10 g protein, 42 g carbohydrates, 10 g fat, and 800 mg sodium. These are approximate figures based on common ingredient labels and the listed portions; brands, rice yield, and how much glaze stays in the pan can change the totals. Check product labels or use a recipe nutrition calculator for a more precise estimate.
Why is Spam musubi high in sodium?
Both Spam and soy sauce contain sodium, and their amounts vary by product. Choosing a lower-sodium Spam option if available, using low-sodium soy sauce, and keeping the glaze modest can reduce the total, but the finished musubi will still be a savory, salty dish.
Can I make Spam musubi ahead of time?
Yes. Assemble it, wrap each piece, and refrigerate promptly for up to 3 to 4 days. The rice becomes firmer in the refrigerator, so for the best texture you can cook the rice and sear the Spam ahead, then assemble shortly before serving.
Can I use sushi rice or another kind of rice?
Sushi rice is short-grain rice and works well here. Medium-grain rice can also hold together, but the result may be less sticky. Avoid basmati or other long-grain varieties if you need the musubi to keep its rectangular shape.
Do I need to cook the Spam to a particular temperature?
Spam is fully cooked before it is packaged, so there is no raw-meat minimum temperature required for this browning step. Heat it until the slices are browned and the glaze is hot and glossy. Follow the package directions after opening and refrigerate unused portions promptly.
How do I keep the nori from getting soggy?
Wrap the musubi as close to serving as practical and keep the nori sheets sealed and dry until use. If packing ahead, store the nori separately and wrap just before eating for the crispest texture.
