The national snack manufacturer has finally secured its legendary curry puff recipe inside a subterranean vault, presumably to prevent the secret ratio of grease-to-potato from falling into enemy hands.

The high-security facility features biometric scanners, laser grids, and a moat filled with boiling peanut oil to protect the 70-year-old document.

"We cannot let people know the secret is just double-fried MSG and heart palpitations," whispered a senior company bean counter.

Locals remain supportive of the extreme measures.

"Liddat good lor, later people steal our lobang then we got nothing to eat during tea break," said one greasy-fingered snack enthusiast.

Officials confirmed the recipe is now officially more guarded than the national reserves or the integrity of most local politicians.
