Yes, blanching is an effective method for loosening the skin of fruits and vegetables like tomatoes and almonds, making them easier to peel.
Blanching involves briefly immersing food in boiling water, followed by an immediate transfer to ice water (an ice bath). This process causes the skin to separate from the flesh due to the rapid temperature change. For tomatoes, score an 'X' on the bottom before blanching for about 30-60 seconds. Then, transfer them to ice water. The skin should peel off easily from the scored area. For almonds, blanching for about 1-2 minutes softens the outer brown skin, allowing it to be easily slipped off by pinching the almond. The hot water loosens the skin, while the ice bath stops the cooking process and further aids in skin separation.
Avoid over-blanching, as this can make the fruit or vegetable mushy. The blanching time depends on the item and its ripeness; start with shorter times and adjust as needed.
