Marriage & pairing
The words marriage and pairing are used for a harmony between sake and food (including snacks, appetizers and others). Marriage comes from a French word mariage meaning marriage, which then came to be used for wine to mean an ideal match or harmony of wine and food. However, marriage does not mean you just simply match foods that go well with drinks or vice versa. It implies that two different materials, forms or colors are mixed to create a new harmony. When it comes to a marriage of foods, it means we can enjoy changes in the aroma and tastes by matching; matching different flavors and tastes to develop each features or by matching something apparently unexpected to negate respective disadvantages.
As for the word pairing, it seems to mean the same as marriage but strictly speaking, it is slightly different. Pairing means a matching of sake and food, or sake and other materials in order to enjoy the harmony rather than changes. It is interesting that preferences of each of us and images we envision are reflected on the pairing.
