Why hummus works better than most vehicles
Hummus has a unique combination of spirulina-masking properties:
- Tahini fat content (~25% fat by weight):The highest fat concentration of any common condiment base. Lipid micelles trap and retain volatile dimethyl sulphide and methanethiol (the primary spirulina off-notes) more effectively than lower-fat matrices.
- Lemon acid:Citric acid in fresh lemon juice (pH 2–2.5) protonates the thiol and amine compounds in spirulina, reducing their vapour pressure and volatility during eating. This is the same principle behind using citrus to “deodorise” fish smells.
- Garlic allicin:One of the most potent aromatics in cooking — allicin and diallyl disulphide dominate any olfactory environment they’re in. At 2+ garlic cloves per batch, spirulina simply cannot compete.
- Cumin:Cumin’s pyrazine and terpenoid aromatics add another layer of flavour complexity that overwhelms subtle notes.
Classic spirulina hummus
Makes approximately 400 g (8 servings). 1 g spirulina per serving.
- 400 g cooked or canned chickpeas (drained)
- 3 tbsp tahini
- Juice of 1.5 lemons
- 2–3 garlic cloves
- 3 tbsp olive oil
- 8 g spirulina powder
- 1 tsp cumin
- ½ tsp salt
- 4–5 tbsp cold water
Blend chickpeas, tahini, lemon, garlic, cumin, and spirulina first — before adding water. This ensures spirulina disperses evenly through the fat matrix rather than remaining in pockets. Add oil and water gradually while blending until smooth and creamy. Taste and adjust lemon, salt, and garlic.
The colour: vivid blue-green when freshly made, shifting to a deeper teal over an hour as phycocyanin fully disperses. After 24 hours refrigeration, the colour stabilises to a dark teal-green. Serve with a drizzle of olive oil, smoked paprika, and sumac on top.
Roasted red pepper spirulina hummus
Adding roasted red pepper creates a deeper flavour profile that masks spirulina at higher doses — and the orange-green colour combination is visually striking.
- All ingredients from classic recipe above
- 1 large roasted red pepper (jarred or freshly roasted)
- Increase spirulina to 10 g (the pepper flavour compensates for the higher dose)
- Add ½ tsp smoked paprika
Blend red pepper into the base before adding water. The resulting colour is a warm brown-green — less obviously “spirulina green” and more a natural-looking earthy hummus colour.
Extra-garlicky spirulina hummus (maximum masking)
For maximum taste masking — intended for those who are particularly sensitive to spirulina flavour or for higher-dose batches.
- Use 5 garlic cloves instead of 2–3
- Add 1 tbsp za’atar blend (thyme, sumac, sesame) — the herb complexity adds another aromatic layer
- Use 12 g spirulina (1.5 g per serving)
Rest the finished hummus for 30+ minutes before tasting — the flavours integrate and the spirulina taste fades further as volatile compounds are absorbed into the fat matrix.
Nutritional upgrade from spirulina
Per 50 g serving of spirulina hummus at 8 g spirulina per batch:
- Protein: 5–6 g (3 g from chickpeas + 0.75 g from spirulina + 1 g from tahini per serving)
- Iron: approximately 1.5–2 mg (chickpeas + spirulina combined)
- The hummus base is already iron-containing (chickpeas, tahini) — spirulina amplifies this, creating one of the highest plant-source iron snacks per serving
- Lemon vitamin C in the recipe enhances non-haem iron absorption from both chickpeas and spirulina — the recipe is structurally optimal for iron bioavailability
Storage
- Refrigerate in airtight container with olive oil covering the surface — prevents oxidation and colour fade
- Use within 5 days — spirulina phycocyanin degrades gradually in the acid environment of stored hummus; colour will shift from teal to more muted green over days
- Freeze in portions — spirulina hummus freezes well. Thaw in fridge overnight and stir before serving
