Why 42%
Butter?

Lowrey Original Butter Cookies use 42% New Zealand cultured butter because this level gave us the balance we wanted: pronounced butter flavour, a delicate melt-in-the-mouth texture and enough structure to retain the piped shape during baking.

The 42% figure applies specifically to Original. Other Lowrey flavours use their own recipes and butter percentages.

Most people think
more butter means
a better cookie.

It doesn't.

How much butter is enough?

Butter brings flavour, aroma and richness to a butter cookie. But the complete recipe must also create the intended texture and give the dough enough structure to retain its shape during baking.

For Lowrey Original, we wanted pronounced cultured-butter character together with a delicate, very fragile and melt-in-the-mouth texture—not a hard or crunchy cookie. The piped swirl still needed to remain recognisable after baking.

More butter can make a cookie richer.
It does not automatically make it better.

The question was not how much butter we could add. It was how much the Original recipe needed.

Every version changed more than one thing.

In tests of the Original recipe, versions with less butter held their shape more readily but did not give us the butter character we wanted.

Versions with more butter tasted richer, but the dough became softer and more difficult to control.

In our Original recipe tests, versions above 45% butter spread too far during baking and no longer retained the piped shape we wanted.

Why Lowrey Original stops at 42% butter.

At 42%, Lowrey Original reached the balance we were looking for: cultured-butter flavour, a delicate crumb, a melt-in-the-mouth texture and enough structure for the piped shape to remain recognisable after baking. This does not mean 42% is the right level for every Lowrey flavour. Each flavour has its own recipe and balance.

Less

The dough held its shape more readily, but the butter character was quieter than we wanted.

42%

The balance chosen specifically for Lowrey Original Butter Cookies.

More

The butter flavour became richer, while the dough became softer and harder to control.

45%+

In our Original tests, the dough spread too far and lost the piped shape we wanted.

Stop

The recipe was not about adding the most butter. It was about finding enough.

42% isn't
a marketing
number.

It is where our search for the Original recipe ended.

We did not choose 42% because the number sounded impressive. We chose it because, in our testing, it produced the balance intended for Lowrey Original.

Pronounced cultured-butter flavour. A delicate, fragile crumb. A melt-in-the-mouth texture. Enough structure to retain the piped swirl during baking.

Beyond that point, adding more butter changed the shape and texture we were trying to create. The recipe no longer behaved like the Lowrey Original we wanted to make.

That is why 42% matters here—not because more is always better, but because enough can be harder to find than more.

The Lowrey Principle

We don't chase more.

We look for the point
where nothing needs adding
and nothing needs taking away.
