The salt is non-negotiable—Diamond Crystal kosher salt dissolves cleanly and gives consistent results. I grab mine in bulk from Costco since it’s the best price for the quantity. Water quality matters too; filtered or distilled prevents off flavors. The vinegar adds brightness (white or apple cider both work), but don’t skip it—it balances the salt beautifully.
No kosher salt? Table salt at half the amount works in a pinch, but it’s denser so measure carefully. Swap vinegar for lemon juice if that’s what’s in your fridge. Brown sugar is optional but adds a subtle caramel note—coconut sugar if you prefer. Skip the baking soda if you’re sensitive to its flavor, though it really does boost crispiness.
This brine keeps indefinitely at room temperature—stored in a clean glass jar, it’s ready whenever you need it. No fridge needed. I make a double batch so I’m never caught without it for spontaneous fry nights.

Step-by-Step Instructions for Potato Brine
This method ensures perfectly crispy results every time with just a few simple steps.
Step 1: Combine Water and Kosher Salt
In a large pot, pour in the 4 cups Water and add the 0.5 cup Kosher Salt. Stir until the salt is fully dissolved—this creates the brine base that will season the potatoes deeply and help them retain moisture during cooking.
I like to use warm water here to speed up the dissolving process, but room temperature works fine too. The key is making sure there are no visible salt crystals left before moving on.
Step 2: Add Aromatics and Acidic Elements
Stir in the 0.25 cup White Vinegar, 1 tbsp Brown Sugar, 1 tbsp Lemon Juice, 1 tsp Black Peppercorns, and 2 pieces Bay Leaves. The vinegar and lemon juice brighten the flavor, while the sugar and aromatics add subtle complexity.
Lightly crush the black peppercorns with the flat side of your knife before adding them—this releases their essential oils for maximum aroma. The bay leaves should be added whole to infuse gently without overpowering.
Step 3: Incorporate Baking Soda for Extra Crispiness
Add the 0.5 tsp Baking Soda and stir to combine. This is the secret ingredient that raises the pH of the potatoes’ surface, allowing them to brown more deeply and develop that coveted crispy exterior when cooked.
You’ll notice the mixture might foam slightly when the baking soda is added—that’s normal. Just give it a good stir until the foaming subsides.
Step 4: Submerge Potatoes and Brine
Add your peeled and cut potatoes to the brine, making sure they’re completely submerged. Use a plate or bowl as a weight if needed to keep them under the liquid. The potatoes should soak for at least 30 minutes at room temperature, or up to 24 hours in the refrigerator for maximum flavor penetration.
For best results, I recommend brining for at least 1 hour. This gives the salt and aromatics enough time to work their magic. You’ll notice the potatoes will look slightly translucent at the edges when they’re ready.
Remove the potatoes from the brine and pat them thoroughly dry with paper towels before cooking. This drying step is crucial for achieving that perfect crispy texture.
Pro Tips For Making Potato Brine
- Dissolve Salt First: I learned this the hard way—mix the kosher salt into the warm water first before adding other ingredients, otherwise you’ll get grainy undissolved bits in your brine.
- Balance the Vinegar: After ruining a batch with too much tang, I now use 1/4 cup white vinegar per quart of water—just enough to brighten the flavor without overpowering.
- Skip Cold Water: Cold water struggles to dissolve the brown sugar and salt evenly, so always start with warm or hot water to guarantee a smooth, consistent brine.
- Add Baking Soda Last: Sounds weird, but it works: stir in the baking soda after the brine has cooled slightly to prevent it from reacting too aggressively with the vinegar.
