HELPFUL TIP: It’s preferable to buy whole beans and stir clear from trimmed or pre-packaged beans. No matter the color or the variety, you need to prep them by trimming them. Make sure you do this just before you need to use them as they tend to oxidise and dry out quickly. Before trimming them, you need to sort them out first, making sure you remove the damaged ones. When you’re left with whole, undamaged ones, you can gather a handful of them at the time. Line up their stems and then trim them off with a knife. Discard the stems, and set the cut beans off to the side.
