There is a setting by Brian Holmes, in his song cycle THERMODYNAMICS, of
John Updike's poem "Cocoa" (text below) that seems appropriate.

John Updike

The scum has come
My cocoa's cold.
The cup is numb
And I grow old.

It seems an age
Since from the pot
It bubbled beige
And burning hot-

Too hot to be
Too quickly quaffed
I found a draft

And in it placed
The boiling brew
And took a taste
Of toast or two

Alas. Time flies
And minutes chill
My cocoa lies
Dull brown and still

How wearisome!
In likelihood,
The scum, once come,
Is come for good.

Some songs about passion that including "boiling", "flaming", and similar

Jean Berger: "My love is like to ice, and I to fire", from AMORETTI

Glinka: Somnenije (Doubt)

English translation:

Be stopped, restlesness of passion!
Fall asleep, hopeless heart!
I weep, I suffer,
The soul is tired of separation;
I suffer, I weep,
Not to sob the grief into tears.
In vain hope to me happiness looks,
I do not believe, I do not believe insidious vows!
Separation takes away love.

Like a sleep persistent and terrible,
I dream of my happy rival,
And secretly and maliciously
boiling jealousy blazes,
And secretly and maliciously
my hand searches for a weapon.
In vain jealousy brings treason to me,
I do not believe, I do not believe the insidious slander.
I am happy: you are mine again.
Sadly the time passes,
we again embrace each other,
And passionately and hotly my happy heart throbs again,
And passionately and hotly our lips melt together.

Gary Bachlund: "A Seal Upon Your Heart", No. 5 from SONG OF SONGS
Paul Gibson: "Infinite Fires", No. 2 from STRONG AS DEATH

The above are two settings of different adaptations of Song of Songs 8:6-7, i.e.
(Revised Standard Version translation):
Set me as a seal upon your heart,
as a seal upon your arm;
for love is strong as death,
jealousy is cruel as the grave.
Its flashes are flashes of fire,
a most vehement flame.
Many waters cannot quench love,
neither can floods drown it.)

And one about candied rose petals, with lovemaking imagery in it:

Julián Aguirre: "Rosas orientales" - from CANCIONES ARGENTINAS, Op. 51
