Mine are sniffing the bottle of toasted sesame oil, just love it!
And then Barbour wax jacket smell makes me feel I'm cuddling up to my lovely DH on a cold day.

Grass
Rain
Creosote

Neon tranquility candle
Coffee
Sourdough bread

Proper lavender (not lavender scented things)
Geranium leaves

The London Underground. Not the bodies and the sweat, that smell as you go down the escalators.

Aircraft fuel. Smells of leaving. And returning.

Rain, turmeric, creosote, camp fires, sea air, tinsel, that smell that the dc have at the end of a warm day (a mix of sun cream, warm skin and outside)

4711 perfume.reminds me of my granny waking me up in the morning by flinging holy water at me and saying morning prayers.

Molton Brown Black Peppercorn reminds me of home.

The cat's fur.

Kouros aftershave takes me back and makes my stomach flip.

Vanilla

Freshly cut grass-reminds me of summer!

Washing dried on the line
Woodsmoke on a crisp, cold day
Skin after a day at the beach
Soil (as in what plants grow in)
Old books/bookshops

Chlorine

Patchouli and amber candles and horse poo

Freshly baked bread, takes me back to memories of my great grandmothers house in Lakenheath.
Woodsmoke
Newly cut grass
The smell of the feet of my boxer dogs and their heads.
The smell of tangerines and cigars, always means Christmas to me.
A certain type of pipe tobacco, I've no idea what it's called, I can't really accost elderly pipe smoking men in public and ask them what is their choice of tobacco, but that smell will always remind me of my Grandad.

OP, if you like the smell of sesame oil you should try a luuuuurvely eau de toilette by Anima Vinci -- Sesame Chan. I had a sample when I ordered some perfume and it was really nice.

Pears Soap - it reminds me of my grandmother.

Real fires
Coconut
Lily of the Valley
Rain on soil in the summer

Opening new jar of coffee and DH going out aftershave

The sea, my childrens hair, fairground smell (diesel generators, candy floss, toffee apples, fried onions, hotdogs and ratburgers) first cup of tea on a morning.

Cigarette smoke and engine oil are two of the foulest scents on earth, but they are my father and transport me back to 1980-something with the faintest whiff of either.

My mums grouting
DPs armpits
Mint and lemon tea
