Dairy products like yogurt, cream, or coconut milk can help counter the spiciness. Stir in a few spoonfuls of yogurt or cream, or add coconut milk to your curry. These ingredients not only cool down the heat but also add richness to the dish.

Tomatoes can provide a natural sweetness that can balance out the spiciness. Add some chopped tomatoes, tomato puree, or canned tomato sauce to your curry.

A touch of sweetness can help mellow the spiciness. Add a small amount of sugar, honey, or even jaggery to the curry and adjust to taste. Keep in mind that you should add sweetness gradually to avoid making the curry too sweet.

Squeeze some fresh lemon or lime juice into the curry. The acidity can help cut through the spiciness and provide a fresh, bright flavor.

Potatoes can absorb some of the heat. Cut them into chunks and add them to your curry. They will become softer and less spicy as they cook.

If your curry is too spicy, serve it with plain bread, rice, or another mild side dish. The starch can help balance out the heat.

To dilute the spiciness, you can add more of the base ingredients of your curry, such as more vegetables, meat, or legumes.

If your curry is too spicy, don't try to fix it all at once. Gradually add the balancing ingredients and taste as you go to ensure you achieve the desired level of spiciness.

If you can identify the source of the excessive spiciness, like whole chili peppers, try to remove them. Be cautious while doing this to avoid any accidental contact with your skin or eyes.

When serving the curry, provide cooling accompaniments like cucumber raita, plain yogurt, or a side of sliced cucumbers. These can help counterbalance the heat.

It's easier to tone down the spiciness in curry by gradually adjusting the flavors rather than trying to neutralize it all at once. Tailor these techniques to your specific curry and personal taste preferences.
