One Reddit user speculated that the different effects of the Kirkland butter might have something to do with a change in its water content, a sentiment echoed on another Reddit thread comparing it to Kerrygold. Since many customers reported crumbly pie doughs this year, a dearth of moisture might be the culprit. Still, there’s no way of knowing exactly since the label on the box does not disclose the exact percentages of its ingredients.
To prevent further baking disasters, some Costco members have contacted the bulk retailer to ask if any changes have been made to its butter. For now, customers will have to appraise the butter (and its box featuring colorful text) themselves to see if it also affects their baking projects.
When a beloved product changes, it can be devastating in more ways than one, so if you’re a fan of Kirkland’s butter, it’s understandable if this news hits hard. But who knows, you might like the allegedly updated version.
