About this site

BlueberryCalculator.com is a free reference for blueberry measurement and cooking. It currently hosts 13 calculators and 40 recipes, and it is published by Neal Media & Production.

Why this exists

Blueberry questions are unusually hard to answer well. How many berries are in a cup? How much fruit does a 9-inch pie actually need? If a recipe calls for two pounds and your scale is broken, what does that look like in a mixing bowl? Search results for questions like these tend to be a thicket of contradictory numbers wrapped in a thousand words of preamble.

We built the thing we wanted instead: a set of calculators that answer one question each, immediately, from a stated and consistent basis — plus recipes that start with the ingredient list rather than a childhood anecdote.

What we publish

Calculators. Each one runs entirely in your browser and works from the same reference berry, so results are consistent across the site. The methodology page documents exactly which figures we use and where they come from.

Recipes. Ingredients, steps, two photographs, and the occasional note explaining why a step matters. Where a recipe pairs with a calculator — scaling muffins, sizing a pie dish, estimating jam yield — we link them directly.

Articles. Longer explanations for questions that need more than a number: storage, freezing, substitutions, and why blueberry baked goods sometimes turn green.

How we handle accuracy

Every calculator is built on published reference data rather than estimates we invented, and the underlying constants are stated openly so you can check our work or substitute your own figures.

We are also honest about the limits. A median berry is a statistical convenience, not a real object — actual blueberries vary by cultivar, season, and ripeness, and wild berries are markedly smaller than cultivated ones. Our results are good estimates, not measurements of your specific fruit.

Recipes carry a TESTED stamp only after they have been cooked in our own kitchen. Untested recipes are developed from established technique and clearly carry no stamp. We would rather show you which is which than pretend everything has been through the oven.

How the site is funded

BlueberryCalculator.com is free and supported by advertising. Ads never determine which recipes we publish or what a calculator returns. If we ever add affiliate links or sponsored content, they will be labeled as such on the page where they appear.

Corrections

If a number here looks wrong, we want to know — a measurement site that will not take corrections is not worth much. Email nealmedia@yahoo.com with the page and the figure you are questioning, and we will check it against our sources and correct it if you are right.
