Winter QoTD #11

People used to say the name of this food item, in an attempt to capture the ideal facial expression while taking a photo. A post even said that this helped keep the mouth “prim”. Belonging to the rose family, they’re used in both desserts and main dishes, can be made into juice or alcohol, eaten raw, or incorporated while baking. 

What is this food item that used to be the go-to word while capturing photographs, before people started saying Jerry’s favourite food?
