You are a chef preparing a special sauce for a dinner party. The recipe requires a specific blend of ingredients mixed in a particular order. You have four ingredients: A, B, C, and D. The instructions are: 'Mix ingredient A with ingredient B, then add ingredient C, and finally mix in ingredient D.' However, the mixing bowl can only hold a maximum of two ingredients at a time. What is the minimum number of mixing steps required to follow the recipe?

Solution
4 steps — Step 1: Mix A and B together (the bowl holds two ingredients). Step 2: Remove B and add C, mixing A with C (still two ingredients). Step 3: Remove A and add D, mixing C with D. Step 4: Finally, combine the two mixtures (A‑B and C‑D) by swapping the remaining single ingredients, which requires one more mixing action. In total, four distinct mixing actions are needed to respect the two‑ingredient limit while preserving the required order, so the answer is 4 steps.
