Stage 1 — Before cooking: predict
Hollandaise is an oil-in-water emulsion. Egg yolk contains emulsifiers that help dispersed butterfat droplets remain suspended in the sauce's water-based phase.
Your recipe book: Hollandaise for Eggs Benedict (4 servings)
- 3 egg yolks
- 1 tablespoon apple cider vinegar
- 250 g clarified butter, lukewarm
- Juice of ½ a lemon
- Sea salt, to taste
Your method uses a bowl over gently simmering water, constant whisking and gradual butter addition. The bowl is removed from the heat before butter is incorporated.
Investigation question: How do temperature, butter addition and whisking influence the stability of hollandaise sauce?
Stage 2 — Run a virtual sauce experiment
Change the conditions, then select Run simulation. Try several combinations and save trials for comparison.
A teaching-model estimate of sauce temperature, not a food safety target or recipe instruction.
For the real practical, follow your teacher's directions and the recipe's gentle-heat method. This simplified model does not provide safe holding temperatures or replace food safety instructions.
Ready to experiment
Select the conditions and run a simulation to see the predicted outcome.
