Yes, leftover egg curry can be frozen with yolks intact, but the texture of the yolks may change, becoming slightly rubbery or grainy upon thawing.
Freezing egg curry is generally safe and can extend its shelf life. However, the freezing process affects the texture of cooked egg yolks. When frozen, the water inside the yolk forms ice crystals. Upon thawing, these ice crystals disrupt the yolk's structure, leading to a change in texture. The yolks might become slightly rubbery, grainy, or even chalky. The curry sauce itself usually freezes well, but ingredients like potatoes might also become a bit mushy. To minimize texture changes, ensure the curry is cooled completely before freezing. Package it in airtight containers or freezer bags, removing as much air as possible to prevent freezer burn. When thawing, do so in the refrigerator overnight for best results. Reheat thoroughly before serving.
To improve the texture of the thawed egg curry, consider adding a small amount of fresh cream or coconut milk during reheating. This can help to re-emulsify the sauce and mask any textural changes in the yolks.
