Lemon

A citrus powerhouse that brightens every dish it touches. Lemon juice adds acidity and freshness, while the zest (outer peel) contains intensely flavored oils. A squeeze of lemon is often the missing ingredient when something tastes 'flat.'

📍

Where to Find It

Produce section, near other citrus (limes, oranges). Sold individually or in mesh bags. Bottled lemon juice is in the juice aisle or near the produce section — decent for cooking but fresh is always better.

How to Pick a Good One

Heavy for their size (more juice). Bright yellow, smooth thin skin. Avoid hard, thick-skinned lemons — they have less juice. A slight give when squeezed is good. Meyer lemons are sweeter and less acidic — a different experience than standard Eureka/Lisbon lemons.

Prepping Tips

Roll on the counter with pressure before cutting — loosens the juice sacs for more yield. Microwave for 10 seconds for even more juice. Zest BEFORE juicing (much easier). Use a microplane for fine zest. Avoid the white pith — it's bitter.

Frequently Asked Questions

How much juice is in one lemon?

A medium lemon yields about 2-3 tablespoons of juice. A large lemon can give up to 4 tablespoons. Roll the lemon firmly on the counter before cutting and microwave for 10 seconds to maximize yield.

Can you freeze lemon juice?

Yes, and you should! Freeze in ice cube trays (about 1 tablespoon per cube), then pop into a zip-lock bag. Lasts 3-4 months. Thaw at room temperature or toss frozen cubes directly into soups, sauces, and dressings.

What is the difference between lemon zest and lemon juice?

Juice provides acidity and tartness. Zest (the outer yellow peel, grated finely) provides concentrated lemon flavor and aroma from essential oils — without the sourness. Many recipes call for both because they do different things. Always zest before juicing.
