🥪Mrs. Clay’s Homemade Sandwich Mayo🥪

Classic • Creamy • Kid-Approved • No Store Run Required

There are moments in the kitchen that feel unexpectedly empowering — and making mayonnaise from scratch is one of them.

It usually happens right as lunch is coming together. The bread is sliced, the meat is warm, everyone is hungry… and the mayo jar is empty. On days like that, running to the store feels exhausting. But knowing I can make a fresh batch in just a few minutes? That feels like a quiet little victory.

This mayonnaise is smooth, familiar, and dependable — the kind that tastes like what your kids already love. It’s not fancy or sharp. It’s not meant to compete with the sandwich. It simply belongs there, tying everything together the way store-bought mayo does… only fresher.

Once you make it a time or two, it becomes one of those kitchen skills that brings a lot of peace.


🥄 What This Mayo Is (and What It Isn’t)

This recipe is intentionally designed to mimic a Hellmann’s / Kraft-style flavor — mild, lightly sweet, and neutral.

✔ Smooth and creamy
✔ Kid-approved
✔ Perfect for subs and sandwiches
✔ No lemony tang
✔ No sharp vinegar bite

This is not an aioli.
This is sandwich mayo.


🥄 What You’ll Need to Know Before You Start

  • Room temperature ingredients matter — especially the egg
  • Neutral oil is best (canola, avocado or light olive oil)
  • An immersion blender is the easiest method
  • This is a small batch, perfect for home use

🥣 Mrs. Clay’s Homemade Sandwich Mayo

Gather Your Ingredients

  • 1 large egg, room temperature
  • 1 cup canola oil
  • 2 teaspoons white vinegar
  • ½ teaspoon salt
  • ¾ teaspoon sugar
  • Optional safety net: tiny pinch baking soda (⅛ teaspoon or less)

Why canola oil?
Because it’s neutral. Olive oil will never give the familiar store-bought flavor kids expect.


🥄 Step-by-Step with Mrs. Clay

  1. Add the egg, canola oil, vinegar, salt, and sugar to a tall jar or container.
  2. Place the immersion blender all the way at the bottom.
  3. Turn the blender on and do not move it for 10–15 seconds.
  4. Once the bottom turns thick and pale, slowly lift the blender upward to fully emulsify.
  5. Taste the mayo.
  6. If it tastes slightly sharp or sour, blend in a tiny pinch of baking soda.
  7. Cover and refrigerate at least 30 minutes before using.

That’s it — no whisking, no stress.


🌸 Mrs. Clay’s Tip — Why the Baking Soda Works

Sugar can mask acidity, but it doesn’t remove it.
A very small pinch of baking soda gently neutralizes excess acid, creating the smooth, mellow flavor kids associate with store-bought mayonnaise.

You should never taste the baking soda — if you do, too much was added.
Think pinch, not spoon.


🧰 Quick Troubleshooting

  • Too thin? Blend in 1 teaspoon more oil.
  • Too thick? Blend in 1 teaspoon warm water.
  • Didn’t emulsify? Start with a fresh egg in a clean jar and slowly blend the failed batch into it.

🧾From My Recipe Box to Yours

This is one of those recipes that doesn’t try to impress — it simply makes life easier. It’s the kind of thing you make once out of necessity and then keep using because it works. Quietly. Reliably. Comfortably.

I hope it brings you that same sense of ease — the kind that comes from realizing you already have what you need right there in your kitchen.

💛 A Thought to Close the Day

Sometimes the best recipes aren’t the ones that impress — they’re the ones that quietly disappear because everyone keeps reaching for more. This mayonnaise is one of those small comforts that carries more meaning than it lets on.

May it remind you that even when plans change or ingredients run out, you’re still capable of creating something good — something familiar — something that feels just right.
