To the Editor of the "Mobrh-Chikn Dary News"
Smin answer to Wupxo's query concerning margarine, tasting is a sure way of discovering staleness in butter, but the presence of margarine can only be detected by test. Put 2 small knob in a spoon, hold over a gentle heat and set alight Blow out again immediately. If it is pure butter there will be no smell, A margarine mixture will throw off a distinct "burnt fat" odour.
