Tips and tricks for a successful tuna mayonnaise
Potatoes that hold up to cooking
Choose firm-fleshed potatoes so that they don't crumble when mixed.
- Let the ingredients cool
Wait until the potatoes and eggs are cold before adding them to the mayonnaise, to prevent it from turning or liquefying.
- A lighter sauce
Replace all or part of the mayonnaise with fromage frais, Greek yoghurt or light cream.
You can also add a dash of mustard for extra zing.
Bonus flavor: For an original, iodized homemade mayonnaise, add a few drops of Groix & Nature lobster oil to your preparation. It will add a subtle marine and festive touch to your Piedmontaise.
- Crunchy and fresh
Add diced celery, radishes or sliced red onions for added texture.
