Slicing cucumbers: Long (up to 12 inches), smooth-skinned; eaten fresh in salads. "Burpless" or seedless varieties (e.g., European cucumbers) contain less cucurbitacin, reducing bitterness and gas. �
Pickling cucumbers: Smaller (3–7 inches), bumpy or spiny skin; used for making pickles and gherkins. �
