Crêpe batter with spirulina
- Whisk into liquid first: Whisk spirulina powder into warm (not hot) milk until completely dissolved before adding flour. Spirulina powder disperses easily in warm milk; cold milk takes longer and may leave visible specks. Once mixed into milk, add the remaining wet ingredients (eggs, melted butter), then sift in flour. Whisk until smooth, then rest.
- Rest time: Rest crêpe batter for 30 minutes minimum (up to 2 hours in the fridge). Resting allows gluten strands to relax, producing more tender crêpes. It also allows the spirulina to fully hydrate and integrate into the batter matrix, improving colour uniformity. Rested batter produces noticeably better crêpes than batter cooked immediately.
- Dosing: 3–4 g spirulina per batch (serves 2, approximately 8 crêpes) gives vivid green colour with no taste impact. At 5+ g per batch the colour deepens but mild marine notes begin to emerge in plain crêpes (less an issue with strongly flavoured fillings). Per-serving dose: approximately 0.75–1 g spirulina per 2 crêpes.
- Pan technique: Use a 20–24 cm crêpe pan or non-stick frying pan. Heat to medium-high (180–200°C surface temperature). Lightly butter between crêpes. Pour 60–80 ml batter, immediately tilt and rotate pan to spread thinly. Cook until edges lift (45–60 seconds), flip, cook 20–30 seconds more. Stack on a warm plate; they do not stick together.
Recipe 1: Classic lemon-sugar green crêpes
Serves 2 (8 crêpes). Phycocyanin: none (cooked). Taste verdict: spirulina completely undetectable.
- 125 g plain flour
- 2 eggs
- 300 ml whole milk (warm)
- 30 g melted butter
- 4 g spirulina powder
- Pinch of salt
- 1 tsp caster sugar
Whisk spirulina into warm milk; add eggs and butter. Sift in flour, salt, and sugar; whisk smooth. Rest 30 minutes. Cook in lightly buttered pan. Serve with fresh lemon squeezed and caster sugar sprinkled — the classic French combination completely dominates; spirulina is undetectable. The vivid green colour against white plate is striking.
Recipe 2: Chocolate-banana dessert crêpes
- 125 g plain flour
- 2 eggs
- 250 ml whole milk (warm)
- 50 ml cream
- 30 g melted butter
- 4 g spirulina powder
- 1 tbsp cocoa powder
- 2 tbsp caster sugar
Filling:
- 2 bananas, sliced
- 50 g dark chocolate, melted (cooled below 35°C)
- Whipped cream
Whisk spirulina and cocoa into warm milk. The cocoa produces a deep green-brown colour in the batter that becomes rich chocolate-green in the cooked crêpe. The chocolate and banana filling completely masks any spirulina. Drizzle cooled chocolate sauce over the assembled crêpes. Do not use hot chocolate sauce if including a cold spirulina addition.
Recipe 3: Savoury spinach-cream crêpes
Serves 2 as a main.
- 125 g plain flour
- 2 eggs
- 300 ml whole milk (warm)
- 30 g melted butter
- 4 g spirulina powder
- Pinch of salt and nutmeg
Filling:
- 150 g baby spinach, wilted and squeezed dry
- 100 g crème fraîche
- 50 g Gruyère, grated
- 1 garlic clove, minced
- Salt and black pepper
Savoury crêpes omit the sugar; increase salt and add nutmeg to the batter. The spinach-crème fraîche filling is a natural flavour complement to spirulina (both are chlorophyll-green). Fold crêpes into quarters over the filling and warm briefly in the oven at 160°C for 5 minutes. The Gruyère and garlic entirely dominate the flavour.
Recipe 4: Smoked salmon and cream cheese crêpes
- 125 g plain flour
- 2 eggs
- 300 ml whole milk (warm)
- 30 g melted butter
- 4 g spirulina powder
- Pinch of salt
Filling:
- 100 g smoked salmon
- 100 g cream cheese
- 2 tbsp capers
- 1 tbsp lemon juice
- Fresh dill
Serve green crêpes cold (wrap around filling and roll; no reheating). The green crêpe with pink salmon and white cream cheese is visually striking. Smoked salmon is one of the strongest flavour masking agents for spirulina; the combination is entirely seamless. Cold-assembled crêpes do not preserve phycocyanin (it was destroyed during cooking) but maintain the visual and nutritional qualities.
Recipe 5: Buckwheat-spirulina galettes (savoury)
Traditional Breton galettes use 100% buckwheat flour — naturally gluten-free and robust.
- 150 g buckwheat flour
- 1 egg
- 350 ml water (warm, not milk)
- Pinch of salt
- 4 g spirulina powder
- 15 g melted salted butter
Buckwheat batter requires more water than wheat crêpe batter; the consistency should be very liquid. Rest 1 hour. Cook on a very hot pan. The earthy nutty buckwheat flavour is one of the most effective spirulina masks of any recipe: the two green-earthy flavours complement rather than clash. Classic galette filling: ham, fried egg, and Emmental (the «complète»). The galette is gluten-free and dairy-free (use oil instead of butter).
Tips and storage
- Batter keeps 2 days in the fridge (covered); the spirulina colour deepens slightly on standing — stir before using
- Cooked crêpes stack and keep at room temperature for 1 hour or in the fridge for 2 days (separate with baking paper to prevent sticking)
- Add cold spirulina yogurt as a sauce (not heated) to provide phycocyanin benefit in the same meal
- For vivid colour: avoid baking soda in crêpe batter (crêpes use no leavening); the near-neutral pH of plain batter preserves chlorophyll colour well
