Eggs is eggs

In December new food labelling regulations were introduced.
Which mean that my most important winter job is to find a way of telling customers exactly what's in our food. Or rather whether any ingredients from a list of allergens are involved anywhere.
I gave myself a deadline to do this.
End of January.
I started today.
I do have a question, though.
Do I need to write "contains eggs" after "Egg Mayonnaise"?
The law now demands it, but is there a better way of doing it?
Perhaps I should just insert the word "obviously".

Present and correct.

Yesterday I set out on a new path.
I have been thinking for a while that we should stock gift items at the tea rooms. Not souvenirs, but pretty tea towels, scented candles, boxed soaps - that sort of thing.
For when you're sitting having a cuppa with a friend, realise that it's your sister's birthday tomorrow and the options are a) leave the lovely surroundings and your cup of tea and your friend to drive into town to trawl the shops for a present or b) buy a perfectly lovely thing right here and pick up a card while you're at it.
Yesterday I went to the Top Drawer show at Olympia with a friend who fortunately knows about such things. Whilst my husband is keen to help, his knowledge ("noone buys those diffuser things, do they?") could be improved.
Now I'm sitting at the kitchen table (with a cup of tea) surrounded by brochures, catalogues, leaflets and price lists trying to make decisions.
I am enjoying myself thoroughly.
