Question

Are there any flavorings or ingredients that could break the emulsion? Find out what to avoid adding to your mayonnaise to keep it stable.

Answer 1

Yes, adding too much water, acidic liquids like lemon juice or vinegar too quickly, or strong spices in large quantities can destabilize the emulsion in mayonnaise, causing it to separate.

Detailed Explanation:

Mayonnaise is an emulsion, a stable mixture of oil and water-based liquids (like egg yolk and vinegar or lemon juice) that normally don't mix. The egg yolk acts as an emulsifier, containing lecithin, which helps bind the oil and water together. However, this emulsion is delicate and can be broken by several factors:

1. Excess Water: Adding too much water or watery ingredients can dilute the emulsifier and cause the oil and water to separate.
2. Rapid Acid Addition: Adding acidic liquids like lemon juice or vinegar too quickly or in excessive amounts can shock the emulsion. The acid can interfere with the lecithin's ability to hold the oil and water together. It's best to add acid gradually.
3. Strong Spices: While small amounts of spices are fine, adding large quantities of strong spices, especially dry ones, can absorb moisture and disrupt the balance of the emulsion. Some spices might also contain compounds that interfere with the emulsification process.
4. Temperature Shock: Extreme temperature changes can also break the emulsion. It's best to keep all ingredients at a similar, preferably cool, temperature.

Pro Tip:

If your mayonnaise starts to separate, try whisking in a teaspoon of Dijon mustard. Mustard contains emulsifying properties that can sometimes help to bring the emulsion back together. Add it slowly while whisking vigorously.
