Why does food (and especially a sandwich!) always taste better when someone else makes it? My mother makes a simple but delicious sandwich every day for lunch. Always the same, she slices good hearth bread, slathers it with Hellman's Best Mayo on both slices, adds a few squares of Swiss cheese and piles on several leaves of crunchy lettuce or occasionally baby spinach. On goes the top, and with a slice down the middle, there it is — the perfect sandwich. Whenever I visit her, I look forward to lunchtime when I can share in her delicious daily ritual. So why doesn't the sandwich taste as good when I make it at home?
