Recipe Notes

How To Choose Perfect Produce For This Salad:

Cucumbers: Look for cucumbers with a bright, even colour of skin without dullness or sweating. The cucumber should look fresh. Choose a firm cucumber - firmness should be right through to the tips of the cucumber. Avoid cucumbers with blemishes, soft spots, yellowing, or easily bent.

Tomatoes: The best tomatoes are completely free of bruises and should be a deep, bright red. Tomatoes that looks dull or pale are going to lack flavor. Avoid tomatoes with any discoloration - it could mean rot on the inside.

Red Onion: choose a red onion that is heavy in your hand and firm to the touch. If an onion is soft or has a strong potent odor, then it has passed its peak.

Avocados: Ripe avocados are typically a dark, almost black color. Squeeze the avocado gently- A ripe avocado should yield to firm, gentle pressure, but shouldn’t feel overly soft or mushy
