# My prefix is a formula, my suffix being shared

The following riddle was inspired by what is referred to as "Riley Puzzles / Riddles" (example).

My prefix is a formula,
My suffix being shared.
My infix starts a warm colour,
Though cast away the heat declared.

618 is the number when,
You join my elements;
Find them in a table, then,
My prefix is a consequence.

What am I?

Hint / Bonus Puzzle:

My suffix is the past,
Of what is mostly done to me.
When hot, I will not last;
I must be in a low degree.

As a flavour, I am classed;
Unless there be an allergy.

Dessert or snacks are of my vast,
A purple wear from _______.

Other inspirations include this riddle and this one, too.

Also, I have decided that if you solve for the missing (blank) word in the bonus puzzle, I will award you a $50$ rep bounty (just because I can). However, I will have to wait two days from now to award the bounty (and I think an extra day or two if I first accept the answer).

• just wanna make sure, Desert or Dessert? – Sensoray Aug 10 '18 at 15:43
• @Sensoray oh Jesus, I mean the latter. Sorry about that. I should know a little better... – Mr Pie Aug 10 '18 at 15:45
• The way I always remembered it was, you want more dessert, that's why there are two s's – Joe-You-Know Aug 10 '18 at 15:46
• @Joe-You-Know hahah, thanks for the tip. Those things always get me. I still struggle on spelling words like embarrassment. (I used autocorrect to spell it just then.) – Mr Pie Aug 10 '18 at 15:53

Are you

chocolate?

My prefix is a formula,

CHO (ie. Carbon-Hydrogen-Oxygen, an aldehyde fragment or the elements which compose a carbohydrate)

My suffix being shared.

ATE (you can share food and eat it; also ATE ends both carbohydrate and chocolate - thanks @user477343!!)

My infix starts a warm colour,
Though cast away the heat declared.

COL (start of "WARM COLOUR" without "WARM", ie. start of "COLOUR")

618 is the number when, You join my elements; Find them in a table, then, My prefix is a consequence.

Refers to the fact that chocolate is a carbohydrate and is made up of carbon (element 6), hydrogen (element 1), and oxygen (element 8) on the periodic table. The prefix, as alluded to before, is the combination C-H-O.

As for the bonus,

My suffix is the past,
Of what is mostly done to me.
ATE is the past tense of "EAT", which is what mostly happens to chocolate
When hot, I will not last;
I must be in a low degree.
Chocolate melts at high temperatures and so must be kept cool unless you want it melting on your fingers.

As a flavour, I am classed;
Unless there be an allergy.
Chocolate is delicious and can come in many forms or classes (ie. milk, dark, white, etc.); but some of the ingredients in chocolate (wheat, nuts, milk) can cause allergies
Dessert or snacks are of my vast,
Chocolate is usually found as part of a dessert or snack food
A purple wear from _______.
Could this be CADBURY (a chocolatier whose chocolates are wrapped in purple, usually and whose name quasi-rhymes with allergy?)

• Wow, that was quick. You even got the bonus correct! Was there a line that acted as a dead giveaway, or did you just happen to think in the right mindset? Also, regarding the second line, Rot13(Gur jbeq "pneob-ulqengr" unf gur fnzr fhssvk nf "pubpbyngr" (v.r. ngr); gurl funer gur fnzr fhssvk.

• Thanks! I think 618 was a big help, then after that the rot13(ybj grzcrengherf znqr vg n ovg zber pyrne, naq gur checyr naq eulzvat Pnqohel jvgu nyyretl tbg zr gur erfg bs gur jnl)! Great puzzle! :D – El-Guest Aug 10 '18 at 16:06
