By following this guide, you will learn how to make mayonnaise recipe from scratch using eggs, oil, and acid. You'll master two reliable methods—whisk by hand and blender or food processor—plus practical tips for texture and safety. Key requirements: fresh eggs or pasteurized yolks, neutral oil, lemon juice or vinegar, and a pinch of salt.
What makes mayonnaise an emulsion
An emulsion is a mixture of two liquids that normally don’t blend, like oil and water. In mayonnaise, fat droplets dispersed in a water-based phase create a thick, creamy product. The main trick is to pair a small amount of emulsifier—in mayo, the egg yolk’s lecithin—with a steady, controlled infusion of oil. According to Best Recipe Book, emulsions are sensitive to temperature, timing, and order of addition. If you whisk too quickly or pour oil too fast, the mixture can split or become oily and grainy. The goal is a smooth, glossy texture that coats a spoon and clings to sandwich fillings. You’ll notice that the whisking or blending action gradually pulls oil into the yolk, creating a stable network of tiny droplets. Two broad approaches work: whisking by hand for a classic texture, or using a blender/food processor for speed and consistency. Both methods rely on constant motion and careful attention to thickness as the oil is incorporated.
Essential ingredients and safety considerations
Classic mayonnaise relies on four building blocks: yolk (or pasteurized yolk), oil, acid, and salt. The yolk provides lecithin, the natural emulsifier that stabilizes the mixture. Use a neutral-flavored oil such as light olive oil, canola, or sunflower to keep the mayo from overpowering the dish. For brightness and emulsification, add lemon juice or white wine vinegar in the early stage. Salt enhances flavor and helps with texture perception. Safety matters: raw yolks carry a small risk; therefore, use pasteurized eggs or cook the yolk briefly if your equipment allows. Temperature matters—ingredients at room temperature emulsify more easily than cold ingredients. If you’re pregnant or immunocompromised, select pasteurized yolks and consider commercial substitutes if safety is a concern.
Tools and equipment overview
Your toolkit should be simple and reliable. A sturdy mixing bowl, a balloon whisk, and a measuring jug are enough for the classic whisk method. For a faster, more consistent result, a blender or food processor can do the heavy lifting, but you add the oil more gradually to avoid overheating the emulsification. A digital thermometer helps monitor temperature, especially when working with cold or room-temperature ingredients. Keep a clean towel handy for spills. If you’re attempting a garlic mayo or aioli, a sharp knife and microplane can help mince garlic finely for even flavor distribution. Finally, fresh, good-quality ingredients produce better texture and taste—so start with fresh yolks, freshly squeezed lemon, and high-quality oil.
Two common methods: whisk and blender
The whisk method starts with a yolk in a bowl, whisked with acid and salt. Then oil is added in a slow, thin stream while you whisk vigorously; the emulsion will begin to thicken as droplets are trapped in the yolk’s surface. For a blender or food processor, combine yolk, acid, and salt, then process on low while streaming oil in through the feed tube. The blender method is quicker but can overheat the mixture if poured too fast or processed too long. In both methods, keep your ingredients at consistent room temperature and add oil gradually to avoid separation. Flavor boosters like mustard or garlic can be added in the final stage for a personalized mayo.
Troubleshooting and adjustments
If the mayo curdles or splits, don’t panic. Start with a teaspoon of water or lemon juice to re-wet the emulsion and whisk vigorously. If using a blender, turn off briefly and restart with a small amount of the broken emulsion. Temperature play matters—if your mayo is too thick, whisk in a few drops of water or lemon juice to loosen it slightly and regain smoothness. If it’s too thin, continue emulsifying while adding a bit more oil in a slow, steady stream. Always taste before seasoning; acid and salt levels can be adjusted at the end without breaking the emulsion.
Variations, storage, and safety notes
Garlic mayo (aioli), spicy mayo, or herb mayo are popular twists. To make aioli, blend garlic with yolk and acid before adding oil slowly. For a lighter version, substitute part of the oil with yogurt or water to adjust texture. Homemade mayo keeps in the fridge for about 1 week when kept cold in a clean, sealed container. Always label the container with the date to track freshness. And remember: homemade mayo uses raw eggs—if you’re serving vulnerable groups, consider pasteurized yolks or fully cooked emulsion options.

Steps
Estimated time: Active time: 15-25 minutes; total time varies with method (0-2 hours chilling if needed)
- 1
Gather ingredients and equipment
Arrange all ingredients at room temperature. Measure acid, salt, and oil, and set up a stable workspace with a clean bowl and whisk. Having everything prepared reduces the risk of adding oil too quickly and helps maintain a steady emulsification.
Tip: Organize items in the order you’ll use them to maintain momentum. - 2
Whisk yolk with acid and salt
Place the yolk in the bowl, add acid (lemon juice or vinegar) and salt, then whisk until the yolk looks glossy and slightly pale. This creates a stable base for the emulsion and helps the oil incorporate smoothly.
Tip: Whisk steadily; a calm, consistent motion improves texture. - 3
Begin oil addition slowly
Drizzle oil into the yolk in a very thin, steady stream while whisking vigorously. The goal is a slow emulsification; if you add oil too quickly, the mixture may separate. Stop occasionally to assess thickness and adjust pace.
Tip: If the emulsion starts to thin, pause and whisk until cohesive before continuing. - 4
Continue adding oil and monitor thickness
Keep adding oil gradually, whisking continuously until the mayo is thick and smooth. If using a blender, switch to a low speed and pour oil through the feed tube in a slow stream while the motor runs. Stop when you reach a spoon-coating texture.
Tip: Maintain a consistent temperature for best results. - 5
Season and taste for balance
Taste the mayo and adjust with additional lemon juice or salt as needed. If you want extra flavor, add a small amount of mustard or a garlic paste. Blend briefly to distribute flavor evenly.
Tip: Add flavorings in small increments to avoid overpowering the emulsion. - 6
Store properly
Transfer the finished mayo to a clean jar or container, seal, and refrigerate. Homemade mayo typically lasts about 1 week when kept cold. Label with the date to monitor freshness.
Tip: Keep it refrigerated and avoid cross-contamination with other foods.
