Cucumber Relish

Wash the cucumbers thoroughly under running water, then slice them into thin rounds using a sharp knife or mandoline, maintaining consistent thickness for even brining.

Peel and thinly slice the onions, then core and finely dice the sweet peppers, removing all seeds and white pith for a clean flavor.

Layer the sliced cucumbers in a large colander or strainer, alternating with salt, starting and ending with a layer of cucumbers; let sit for 10 minutes to draw out excess moisture.

Rinse the salted cucumbers thoroughly under cold running water to remove the excess salt, pressing gently to extract any remaining liquid.

Combine the sugar, mustard seed, and celery seed in a large stainless steel pot or non-reactive container.

Pour the vinegar into the pot with the spice and sugar mixture, stirring well until the sugar is completely dissolved.

Add the rinsed cucumbers, sliced onions, and diced sweet peppers to the vinegar mixture, stirring gently to coat all vegetables evenly.

Bring the mixture to a gentle simmer over medium heat, stirring occasionally, and cook until the cucumbers become tender but retain a slight firmness, about 10-15 minutes.

Remove from heat and allow the relish to cool to room temperature, stirring occasionally to ensure even cooling and flavor distribution.

Transfer the cooled relish into sterilized glass jars, ensuring the vegetables are covered by the vinegar liquid, then seal tightly and refrigerate for at least 24 hours before serving to allow flavors to meld.
